Atmosphere to Pound per square inch
Atmosphere (atm)
Pound per square inch (psi)
How it is calculated
Each unit is defined via the base unit (pascal (Pa)). The value is first converted to the base unit, then to the selected unit.
1 atm = 101325 Pa
1 psi = 6894.75729317 Pa
1 atm × 101325 = 101325 Pa
101325 Pa ÷ 6894.75729317 = 14.6959487755 psi
