How to Convert Standard Atmosphere to Pascal

1 standard atmosphere = 101325 pascals exact

Pascal = Standard Atmosphere × 101325

Example: 21.2 atm × 101325 = 2148100 Pa

Reverse Conversion

To convert pascals back to standard atmospheres:

  • Remember, 1 pascal equals 9.86923 × 10-6 standard atmospheres.
  • To convert 2148100 Pa to atm, multiply 2148100 x 9.86923 × 10-6, resulting in 21.2 atm.

exact This conversion factor is exact by international definition.

21.2 atm is also equal to:

  • 2148.1 kPa
  • 21.481 bar
  • 311.55 psi
