English numerals

English number words include numerals and various words derived from them, as well as a large number of words borrowed from other languages.

Cardinal numbers

Cardinal numbers refer to the size of a group. In English, these words are numerals.

0	zero (nought)	10	ten
1	one	11	eleven
2	two	12	twelve (a dozen)	20	twenty (a score)
3	three	13	thirteen	30	thirty
4	four	14	fourteen	40	forty (no "u")
5	five	15	fifteen (note "f", not "v")	50	fifty (note "f", not "v")
6	six	16	sixteen	60	sixty
7	seven	17	seventeen	70	seventy
8	eight	18	eighteen (only one "t")	80	eighty (only one "t")
9	nine	19	nineteen	90	ninety (note the "e")

If a number is in the range 21 to 99, and the second digit is not zero, one typically writes the number as two words separated by a hyphen.

21	twenty-one
25	twenty-five
32	thirty-two
58	fifty-eight
64	sixty-four
79	seventy-nine
83	eighty-three
99	ninety-nine

In English, the hundreds are perfectly regular, except that the word hundred remains in its singular form regardless of the number preceding it.

100	one hundred
200	two hundred
…	…
900	nine hundred

So too are the thousands, with the number of thousands followed by the word "thousand".

1,000	one thousand
2,000	two thousand
…	…
10,000	ten thousand or (rarely used) a myriad, which usually means an indefinitely large number.
11,000	eleven thousand
…	…
20,000	twenty thousand
21,000	twenty-one thousand
30,000	thirty thousand
85,000	eighty-five thousand
100,000	one hundred thousand or one lakh (Indian English)
999,000	nine hundred and ninety-nine thousand (inclusively British English, Irish English, Australian English, and New Zealand English) nine hundred ninety-nine thousand (American English)
1,000,000	one million
10,000,000	ten million or one crore (Indian English)

In American usage, four-digit numbers are often named using multiples of "hundred" and combined with tens and ones: "eleven hundred three", "twelve hundred twenty-five", "four thousand forty-two", or "ninety-nine hundred ninety-nine." In British usage, this style is common for multiples of 100 between 1,000 and 2,000 (e.g. 1,500 as "fifteen hundred") but not for higher numbers.

Americans may pronounce four-digit numbers with non-zero tens and ones as pairs of two-digit numbers without saying "hundred" and inserting "oh" for zero tens: "twenty-six fifty-nine" or "forty-one oh five". This usage probably evolved from the distinctive usage for years; "nineteen-eighty-one", or from four-digit numbers used in the American telephone numbering system which were originally two letters followed by a number followed by a four-digit number, later by a three-digit number followed by the four-digit number. It is avoided for numbers less than 2500 if the context may mean confusion with time of day: "ten ten" or "twelve oh four".

Intermediate numbers are read differently depending on their use. Their typical naming occurs when the numbers are used for counting. Another way is for when they are used as labels. The second column method is used much more often in American English than British English. The third column is used in British English but rarely in American English (although the use of the second and third columns is not necessarily directly interchangeable between the two regional variants). In other words, British English and American English can seemingly agree, but it depends on a specific situation (in this example, bus numbers).

	Common British vernacular	Common American vernacular	Common British vernacular
	"How many marbles do you have?"	"What is your house number?"	"Which bus goes to the High Street?"
101	"A hundred and one."	"One-oh-one." Here, "oh" is used for the digit zero.	"One-oh-one."
109	"A hundred and nine."	"One-oh-nine."	"One-oh-nine."
110	"A hundred and ten."	"One-ten."	"One-one-oh."
117	"A hundred and seventeen."	"One-seventeen."	"One-one-seven."
120	"A hundred and twenty."	"One-twenty."	"One-two-oh", "One-two-zero."
152	"A hundred and fifty-two."	"One-fifty-two."	"One-five-two."
208	"Two hundred and eight."	"Two-oh-eight."	"Two-oh-eight."
394	"Three hundred and ninety-four."	"Three-ninety-four."	"Three-ninety-four." or "Three-nine-four."

Note: When writing a cheque (or check), the number 100 is always written "one hundred". It is never "a hundred".

In American English, many students are taught not to use the word and anywhere in the whole part of a number, so it is not used before the tens and ones. It is instead used as a verbal delimiter when dealing with compound numbers. Thus, instead of "three hundred and seventy-three", one would say "three hundred seventy-three". Despite this rule, the and is used by some Americans in reading numbers containing tens and ones as an alternative variant.

Very large numbers

For numbers above a million, there are three main systems for naming numbers in English (for the use of prefixes such as kilo- for a thousand, mega- for a million, milli- for a thousandth, etc. see SI units):

the long scale (formerly used in British English but now less so) designates a system of numeric names in which a thousand million is called a milliard, and billion is used for a million million. This system is still used in several other European languages.
the short scale (always used in American English and almost invariably in British English) designates a system of numeric names in which a thousand million is called a billion, and the word milliard is not used.
the Indian numbering system, used widely in South Asia.

Number notation	Power notation	Short scale	Long scale	Indian (or South Asian) English
1,000,000	10⁶	one million	one million	ten lakh
1,000,000,000	10⁹	one billion a thousand million	one milliard a thousand million	one hundred crore (one arab)
1,000,000,000,000	10¹²	one trillion a thousand billion	one billion a million million	one lakh crore (ten kharab)
1,000,000,000,000,000	10¹⁵	one quadrillion a thousand trillion	one billiard a thousand billion	ten crore crore (one padm)
1,000,000,000,000,000,000	10¹⁸	one quintillion a thousand quadrillion	one trillion a million billion	ten thousand crore crore (ten shankh)
1,000,000,000,000,000,000,000	10²¹	one sextillion a thousand quintillion	one trilliard a thousand trillion	one crore crore crore

The numbers past one trillion in the short scale system, in ascending powers of 1000, are as follows: quadrillion, quintillion, sextillion, septillion, octillion, nonillion, decillion, undecillion, duodecillion, tredecillion, quattuordecillion, quindecillion, sexdecillion, septendecillion, octodecillion, novemdecillion and vigintillion (which is 10 to the 63rd power, or a one followed by 63 zeros). The highest number in this series listed in modern dictionaries is centillion, which is 10 to the 303rd power.^[1] The interim powers of one thousand between vigintillion and centillion do not have standardized names, nor do any higher powers, but there are many ad hoc extensions in use. The highest number listed in Robert Munafo's table of such unofficial names^[2] is milli-millillion, which was coined as a name for 10 to the 3,000,003rd power.

The googolplex has often been cited as the largest named number in English. If a googol is ten to the one hundredth power, then a googolplex is one followed by a googol of zeros (that is, ten to the power of a googol).^[3] There is the coinage, of very little use, of ten to the googolplex power, of the word googolplexplex.

The terms arab, kharab, padm and shankh are more commonly found in old books on Indian mathematics.

Here are some approximate composite large numbers in American English:

Quantity	Written	Pronounced
1,200,000	1.2 million	one point two million
3,000,000	3 million	three million
250,000,000	250 million	two hundred fifty million
6,400,000,000	6.4 billion	six point four billion
23,380,000,000	23.38 billion	twenty-three point three eight billion

Often, large numbers are written with (preferably non-breaking) half-spaces or thin spaces separating the thousands (and, sometimes, with normal spaces or apostrophes) instead of commas—to ensure that confusion is not caused in countries where a decimal comma is used. Thus, a million is often written 1 000 000.

In some areas, a point (. or ·) may also be used as a thousands' separator, but then, the decimal separator must be a comma (,). In English the point (.) is used as the decimal separator, and the comma (,) as the thousands' separator.

Specialized numbers

A few numbers have special names (in addition to their regular names):

0: has several other names, depending on context:
- zero: formal scientific usage
- naught / nought: mostly British usage
- aught: Mostly archaic but still occasionally used when a digit in mid-number is 0 (as in "thirty-aught-six", the .30-06 Springfield rifle cartridge and by association guns that fire it)

0–0 British English: nil-nil or nil all; American English: zero-zero or nothing-nothing, (occasionally scoreless or no score)
2–2 two-two or two all; American English also twos, two to two, even at two, or two up.

Naming conventions of Tennis scores (and related sports) are different from other sports.

The centuries of Italian culture have names in English borrowed from Italian:

duecento "(one thousand and) two hundred" for the years 1200 to 1299, or approximately 13th century
trecento 14th century
quattrocento 15th century
cinquecento 16th century
seicento 17th century
settecento 18th century
ottocento 19th century
novecento 20th century

Multiplicative adverbs

A few numbers have specialised multiplicative numbers (adverbs) which express how many times some event happens:

one time	once
two times	twice
three times	thrice (largely obsolete)

Compare these specialist multiplicative numbers to express how many times some thing exists (adjectives):

× 1	solitary	singular	one-off
× 2	double	twofold	duplicate
× 3	triple	threefold	triplicate
× 4	quadruple	fourfold
× 5	quintuple	fivefold
× 6	sextuple, hextuple	sixfold
× 7	septuple, heptuple	sevenfold
×100	.....	hundredfold

English also has some multipliers and distributive numbers, such as singly.

Other examples are given in the Specialist Numbers.

Negative numbers

The name of a negative number is the name of the corresponding positive number preceded by "minus" or (American English) "negative". Thus −5.2 is "minus five point two" or "negative five point two". For temperatures, North Americans colloquially say "below"—short for "below zero"—so a temperature of −5° is "five below" (in contrast, for example, to "two above" for 2°). This is occasionally used for emphasis when referring to several temperatures or ranges both positive and negative. This is particularly common in Canada where the use of Celsius in weather forecasting means that temperatures can regularly drift above and below zero at certain times of year.

Ordinal numbers

Ordinal numbers refer to a position in a series. Common ordinals include:

0th	zeroth or noughth (see below)	10th	tenth
1st	first	11th	eleventh
2nd	second	12th	twelfth (note "f", not "v")	20th	twentieth
3rd	third	13th	thirteenth	30th	thirtieth
4th	fourth	14th	fourteenth	40th	fortieth
5th	fifth	15th	fifteenth	50th	fiftieth
6th	sixth	16th	sixteenth	60th	sixtieth
7th	seventh	17th	seventeenth	70th	seventieth
8th	eighth (only one "t")	18th	eighteenth	80th	eightieth
9th	ninth (no "e")	19th	nineteenth	90th	ninetieth

Zeroth only has a meaning when counting starts with zero, which happens in a mathematical or computer science context. Ordinal numbers predate the invention of zero and positional notation.

Ordinal numbers such as 21st, 33rd, etc., are formed by combining a cardinal ten with an ordinal unit.

21st	twenty-first
25th	twenty-fifth
32nd	thirty-second
58th	fifty-eighth
64th	sixty-fourth
79th	seventy-ninth
83rd	eighty-third
99th	ninety-ninth

Higher ordinals are not often written in words, unless they are round numbers (thousandth, millionth, billionth). They are written using digits and letters as described below. Here are some rules that should be borne in mind.

The suffixes -th, -st, -nd and -rd are occasionally written superscript above the number itself.
If the tens digit of a number is 1, then write "th" after the number. For example: 13th, 19th, 112th, 9,311th.
If the tens digit is not equal to 1, then use the following table:

If the units digit is:	0	1	2	3	4	5	6	7	8	9
write this after the number	th	st	nd	rd	th	th	th	th	th	th

For example: 2nd, 7th, 20th, 23rd, 52nd, 135th, 301st.

These ordinal abbreviations are actually hybrid contractions of a numeral and a word. 1st is "1" + "st" from "first". Similarly, "nd" is used for "second" and "rd" for "third". In the legal field and in some older publications, the ordinal abbreviation for "second" and "third" is simply "d".

For example: 42d, 33d, 23d.

NB: The practice of using "d" to denote "second" and "third" is still often followed in the numeric designations of units in the US armed forces, for example, 533d Squadron, and in legal citations for the second and third series of case reporters.

Any ordinal name that doesn't end in "first", "second", or "third", ends in "th".

Dates

There are a number of ways to read years. The following table offers a list of valid pronunciations and alternate pronunciations for any given year of the Gregorian calendar.

Year	Most common pronunciation method	Alternative methods
1 BC	(The year) One Before Christ (BC)	1 before the Common era (BCE)
1	(The year) One Anno Domini (AD)	of the Common era (CE) In the year of Our Lord 1
235	Two thirty-five	Two-three-five Two hundred (and) thirty-five
911	Nine eleven	Nine-one-one Nine hundred (and) eleven
999	Nine ninety-nine	Nine-nine-nine Nine hundred (and) ninety-nine
1000	One thousand	Ten hundred 1K
1004	One thousand (and) four	Ten oh-four
1010	Ten ten	One thousand (and) ten
1050	Ten fifty	One thousand (and) fifty
1225	Twelve twenty-five	One-two-two-five One thousand, two hundred (and) twenty-five Twelve-two-five
1900	Nineteen hundred	One thousand, nine hundred Nineteen aught
1901	Nineteen oh-one	Nineteen hundred (and) one One thousand, nine hundred (and) one Nineteen aught one
1919	Nineteen nineteen	Nineteen hundred (and) nineteen One thousand, nine hundred (and) nineteen
1999	Nineteen ninety-nine	Nineteen hundred (and) ninety-nine One thousand, nine hundred (and) ninety-nine
2000	Two thousand	Twenty hundred Two triple-oh Y2K
2001	Two thousand (and) one	Twenty oh-one Twenty hundred (and) one Two double-oh-one Two oh-oh-one
2009	Two thousand (and) nine	Twenty oh-nine Twenty hundred (and) nine Two double-oh-nine Two oh-oh-nine
2010	Twenty ten^[7]	Twenty hundred (and) ten two-oh-one-oh Two thousand (and) ten

Fractions and decimals

In spoken English, ordinal numbers are also used to quantify the denominator of a fraction. Thus "fifth" can mean the element between fourth and sixth, or the fraction created by dividing the unit into five pieces. In this usage, the ordinal numbers can be pluralized: one seventh, two sevenths. The sole exception to this rule is division by two. The ordinal term "second" can only refer to location in a series; for fractions English speakers use the term 'half' (plural "halves").

Here are some common English fractions (known linguistically as "partitive numerals"):^[8]

1/16	one sixteenth
1/10 or 0.1	one tenth
1/8	one eighth
2/10 or 0.2	two tenths
1/4	one quarter or (mainly American English) one fourth
3/10 or 0.3	three tenths
1/3	one third
3/8	three eighths
4/10 or 0.4	four tenths
1/2	one half
6/10 or 0.6	six tenths
5/8	five eighths
2/3	two thirds
7/10 or 0.7	seven tenths
3/4	three quarters or three fourths
8/10 or 0.8	eight tenths
7/8	seven eighths
9/10 or 0.9	nine tenths
15/16	fifteen sixteenths

Alternatively, and for greater numbers, one may say for 1/2 "one over two", for 5/8 "five over eight", and so on. This "over" form is also widely used in mathematics.

Numbers with a decimal point may be read as a cardinal number, then "and", then another cardinal number followed by an indication of the significance of the second cardinal number (mainly U.S.); or as a cardinal number, followed by "point", and then by the digits of the fractional part. The indication of significance takes the form of the denominator of the fraction indicating division by the smallest power of ten larger than the second cardinal. This is modified when the first cardinal is zero, in which case neither the zero nor the "and" is pronounced, but the zero is optional in the "point" form of the fraction.

For example:

0.002 is "two thousandths" (mainly U.S.); or "point zero zero two", "point oh oh two", "nought point zero zero two", etc.
3.1416 is "three point one four one six"
99.3 is "ninety-nine and three tenths" (mainly U.S.); or "ninety-nine point three".

In English the decimal point was originally printed in the center of the line (0·002), but with the advent of the typewriter it was placed at the bottom of the line, so that a single key could be used as a full stop/period and as a decimal point. In many non-English languages a full-stop/period at the bottom of the line is used as a thousands separator with a comma being used as the decimal point.

Fractions together with an integer are read as follows:

1 1/2 is "one and a half"
6 1/4 is "six and a quarter"
7 5/8 is "seven and five eighths"

A space is required between the whole number and the fraction; however, if a special fraction character is used like "½", then the space can be done without, e.g.

9 1/2
9½

Whether to use digits or words

With few exceptions, most grammatical texts rule that the numbers zero to nine inclusive should be "written out" – instead of "1" and "2", one would write "one" and "two".^[9]

Example: "I have two apples." (Preferred)

Example: "I have 2 apples."

After "nine", one can head straight back into the 10, 11, 12, etc., although some write out the numbers until "twelve".

Example: "I have 28 grapes." (Preferred)

Example: "I have twenty-eight grapes."

Another common usage is to write out any number that can be expressed as one or two words, and use figures otherwise.

Examples:

"There are six million dogs." (Preferred)

"There are 6,000,000 dogs."

"That is one hundred and twenty-five oranges." (British English)

"That is one hundred twenty-five oranges." (US-American English)

"That is 125 oranges." (Preferred)

Numbers at the beginning of a sentence should also be written out, or the sentence rephrased.

The above rules are not always followed. In literature, larger numbers might be spelled out. On the other hand, digits might be more commonly used in technical or financial articles, where many figures are discussed. In particular, the two different forms should not be used for figures that serve the same purpose; for example, it is inelegant to write, "Between day twelve and day 15 of the study, the population doubled."

Empty numbers

"Out of the Mud" flyer.

Colloquial English has a small vocabulary of empty numbers that can be employed when there is uncertainty as to the precise number to use, but it is desirable to define a general range: specifically, the terms "umpteen", "umpty", and "zillion". These are derived etymologically from the range affixes:

"-teen" (designating the range as being between 10 and 20)
"-ty" (designating the range as being in one of the decades between 20 and 100)
"-illion" (designating the range as being above 1,000,000; or, more generally, as being extremely large).

The prefix "ump-" is added to the first two suffixes to produce the empty numbers "umpteen" and "umpty": it is of uncertain origin. There is a noticeable absence of an empty number in the hundreds range.

Usage of empty numbers:

The word "umpteen" may be used as an adjective, as in "I had to go to umpteen stores to find shoes that fit." It can also be used to modify a larger number, usually "million", as in "Umpteen million people watched the show; but they still cancelled it."
"Umpty" is not in common usage. It can appear in the form "umpty-one" (parallelling the usage in such numbers as "twenty-one"), as in "There are umpty-one ways to do it wrong." "Umpty-ump" is also heard, though "ump" is never used by itself.
The word "zillion" may be used as an adjective, modifying a noun. The noun phrase normally contains the indefinite article "a", as in "There must be a zillion pages on the World Wide Web."
The plural "zillions" designates a number indefinitely larger than "millions" or "billions". In this case, the construction is parallel to the one for "millions" or "billions", with the number used as a plural count noun, followed by a prepositional phrase with "of", as in "There are zillions of grains of sand on the beaches of the world."
Empty numbers are sometimes made up, with obvious meaning: "squillions" is obviously an empty, but very large, number; a "squintillionth" would be a very small number.
Some empty numbers may be modified by actual numbers, such as "four zillion", and are used for jest, exaggeration, or to relate abstractly to actual numbers.
Empty numbers are colloquial, and primarily used in oral speech or informal contexts. They are inappropriate in formal or scholarly usage.
