1 psi ≈ 0.0680459639099 atm
1 atm ≈ 14.6959487755 psi

Formula: atm ≈ psi × 0.0680459639099
psi ≈ atm × 14.6959487755

Definitions: 1 psi = 8896443230521/1290320000 Pa; 1 atm = 101325 Pa

The pound per square inch (psi) is the customary United States unit of pressure, one pound-force per square inch. It is used for tire pressure, air compressors and water and gas pressure in the United States, and for tires in the United Kingdom too.

The standard atmosphere (atm) is exactly 101,325 pascals, the average air pressure at sea level. It is a reference pressure in chemistry and physics and is used to express high pressures as multiples of atmospheric pressure.
