Bite force quotient

Bite force quotient (BFQ) is the regression of the quotient of an animal's bite force in newtons divided by its body mass in kilograms.[1][2] It does not take into account sharpness of teeth or other differences in tooth form; an animal with sharp teeth will project its bite force over a small surface area, while an animal with flatter teeth will spread the force out over a larger area.

Hite et al. [3], who include data from the widest range of living mammals of any bite force regression to date, produce from their regression the BFQ equation:

${\displaystyle BFQ=100\left({\frac {BF}{10^{0.5703(\log _{10}BM)+0.1096}}}\right)}$

where BF = Bite Force (N), and BM = Body Mass (g)
