Lot (unit)

A lot is an old unit of weight used in many European countries since the Middle Ages until the beginning of the 20th century. Most often it was defined as either ¹⁄₃₀ or ¹⁄₃₂ of a pound (or more precisely of whatever mass value one local pound had at the time). Recorded values range from 10 to 50 grams.

In the Imperial and US costumary systems of measurement, a lot is ¹⁄₃₂ of a pound, or ¹⁄₂ an ounce, making it exactly 14.174 761 562 5 grams if derived from the international pound.
