How to Convert Psi to Bar

1 psi = 0.0689476 bar

Bar = Psi × 0.0689476

Example: 4990 psi × 0.0689476 = 344.05 bar

Reverse Conversion

To convert bar back to psi:

  • Remember, 1 bar equals 14.5038 psi.
  • To convert 344.05 bar to psi, multiply 344.05 x 14.5038, resulting in 4990 psi.

4990 psi is also equal to:

  • 3.4405 × 107 pascal
  • 34405 kPa
About these units

Psi: Imperial/US customary pressure unit equal to one pound-force per square inch.

Bar: Metric pressure unit equal to exactly 100,000 pascals.
