How do you convert PSI to bar?
Multiply PSI by approximately 0.0689476 to get bar (exact factor uses the defined PSI in pascal divided by 100,000 Pa per bar).
Detailed answer
PSI is pounds-force per square inch, defined against SI length and force so that 1 PSI ≈ 6,894.757 Pa. One bar = 100,000 Pa, so bar = PSI × (6894.757… / 100,000).
Relationship context
US tire and hydraulic specs often use PSI; European equipment and scuba cylinders often use bar.
