Bite force quotient


Bite force quotient is the regression of the quotient of an animal's bite force in newtons divided by its body mass in kilograms. 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., who include data from the widest range of living mammals of any bite force regression to date, produce from their regression the BFQ equation:
where BF = Bite Force, and BM = Body Mass
