Common pitfalls and look-alike units

One standard atmosphere is exactly 101325 Pa while 1 bar is 100000 Pa — about 1.3% apart, so do not mix them. Tire pressures are often quoted in psi or bar (1 bar ≈ 14.5 psi, 1 psi ≈ 6.895 kPa); millimeter of mercury uses the conventional value 1 mmHg = 133.322387415 Pa.

Frequently asked questions

How many standard atmospheres are in a megapascal?
