How do I convert bar to PSI?

Multiply bar by 14.5038 to get PSI. Example: 2 bar × 14.5038 = 29.008 psi. To convert PSI to bar: divide by 14.5038.

What is the difference between bar and PSI?

Bar is a metric unit (used worldwide), PSI (pounds per square inch) is used in the US. 1 bar ≈ 14.5 psi. Tire pressure in Europe uses bar; US uses PSI.
