How to convert Pounds per Square Inch to Atmosphere
1 psi = 1 lbfin2
1 atm = 101,325 Pa
1 psi (psi) is equal to 0.06804596 atmosphere (atm).
atm = psi × 0.06804596
Multiply the pressure in psis by 0.06804596:
Example: Convert 14.696 psi to atm:
atm = 14.696 × 0.06804596 = 1 atm

How this calculator works
The form on this page is a PSI-to-Atmosphere converter. After you enter a number, JavaScript multiplies or rearranges it with the published conversion factor and writes the atm result in the output box. The step-by-step panel repeats the arithmetic so you can copy it into homework or a spreadsheet.
