pound-force per square inch (psi) | |
|---|---|---|---|---|---|
| 1 Pa | ≡ 1 N/m2 | 10−5 | 9.8692×10−6 | 7.5006×10−3 | 145.04×10−6 |
| 1 bar | 100,000 | ≡ 106 dyn/cm2 | 0.98692 | 750.06 | 14.504 |
| 1 atm | 101,325 | 1.01325 | ≡ 1 atm | 760 | 14.696 |
| 1 torr | 133.322 | 1.3332×10−3 | 1.3158×10−3 | ≡ 1 Torr ≈ 1 mmHg |
19.337×10−3 |
| 1 psi | 6,894.76 | 68.948×10−3 | 68.046×10−3 | 51.715 | ≡ 1 lbf/in2 |
Example reading: 1 Pa = 1 N/m2 = 10−5 bar = 10.197×10−6 at = 9.8692×10−6 atm, etc.
Note: mmHg is an abbreviation for millimetre
