1 psi = 0.0680459639099 atm

Show the working
  1. 1 psi = 0.0680459639099 atm
  2. 1 × 0.0680459639099 = 0.0680459639099 atm

How to convert pounds per square inch to standard atmospheres

1 psi = 0.0680459639099 atm, so multiply by 0.0680459639099 to go from pounds per square inch to standard atmospheres. Going the other way, 1 atm = 14.6959487755 psi.

atm = psi × 0.0680459639099
psi = atm × 14.6959487755

Worked example:

1 psi = 0.0680459639099 atm
5 × 0.0680459639099 = 0.340229819549 atm
