How strong is that bite?

Bite force is measured in newtons at the back teeth, where the leverage is greatest. Human bites are unimpressive.

Reference figures are measurements and are rounded; the unit conversion behind them is exact.

great white shark	18,200 N	1/18.2
T. rex	57,000 N	1/57	Estimated from skull mechanics

A saltwater crocodile bites at 16 460 N — the highest ever directly measured in a living animal, and about thirteen times a human.
T. rex is estimated at 57 000 N, enough to crush bone. The estimate comes from muscle reconstruction, not measurement.

Frequently asked

Among living animals, the saltwater crocodile. Extinct contenders — T. rex, Megalodon — are estimated from anatomy and carry large uncertainties.

Because PSI is pressure and depends on tooth area, so it varies across the same bite. Force is the property of the jaw.
