How to Convert Standard Atmosphere to Bar

1 standard atmosphere = 1.01325 bar

Bar = Standard Atmosphere × 1.01325

Example: 15 atm × 1.01325 = 15.199 bar

Reverse Conversion

To convert bar back to standard atmospheres:

  • Remember, 1 bar equals 0.986923 standard atmospheres.
  • To convert 15.199 bar to atm, multiply 15.199 x 0.986923, resulting in 15 atm.

15 atm is also equal to:

  • 1519900 pascal
  • 1519.9 kPa
  • 220.44 psi
