Bar to PSI (bar to psi)
Result
14.50377377 PSI
Formula
psi = bar × 14.50377377
1 bar = 14.50377377 psi, and 1 psi = 0.06894757293 bar.
The pascal is one newton per square metre. The bar is exactly 100,000 Pa, the standard atmosphere exactly 101,325 Pa, the torr exactly 1/760 atm, and psi is one pound-force per square inch (6,894.757 Pa).
Worked examples
- 1 bar × 14.50377377 = 14.503774 psi
- 2.5 bar × 14.50377377 = 36.259434 psi
- 9 bar × 14.50377377 = 130.53396 psi
- 200 bar × 14.50377377 = 2,900.7548 psi
Things to know about bar to psi
- Multiply by 14.5038. Espresso machines brew at about 9 bar (130.5 psi); a full scuba tank is about 200 bar (2,900 psi).
- One bar is slightly less than one standard atmosphere (1.01325 bar).
