How to Convert Standard Atmosphere to Pascal

1 standard atmosphere = 101325 pascals exact

Pascal = Standard Atmosphere × 101325

Example: 12 atm × 101325 = 1215900 Pa

Reverse Conversion

To convert pascals back to standard atmospheres:

  • Remember, 1 pascal equals 9.86923 × 10-6 standard atmospheres.
  • To convert 1215900 Pa to atm, multiply 1215900 x 9.86923 × 10-6, resulting in 12 atm.

exact This conversion factor is exact by international definition.

12 atm is also equal to:

  • 1215.9 kPa
  • 12.159 bar
  • 176.35 psi
