How to Convert Standard Atmosphere to Bar

1 standard atmosphere = 1.01325 bar

Bar = Standard Atmosphere × 1.01325

Example: 13 atm × 1.01325 = 13.172 bar

Reverse Conversion

To convert bar back to standard atmospheres:

  • Remember, 1 bar equals 0.986923 standard atmospheres.
  • To convert 13.172 bar to atm, multiply 13.172 x 0.986923, resulting in 13 atm.

13 atm is also equal to:

  • 1317200 pascal
  • 1317.2 kPa
  • 191.05 psi
