How to Convert Standard Atmosphere to Pascal

1 standard atmosphere = 101325 pascals exact

Pascal = Standard Atmosphere × 101325

Example: 18.8 atm × 101325 = 1904900 Pa

Reverse Conversion

To convert pascals back to standard atmospheres:

  • Remember, 1 pascal equals 9.86923 × 10-6 standard atmospheres.
  • To convert 1904900 Pa to atm, multiply 1904900 x 9.86923 × 10-6, resulting in 18.8 atm.

exact This conversion factor is exact by international definition.

18.8 atm is also equal to:

  • 1904.9 kPa
  • 19.049 bar
  • 276.28 psi
About these units
