Formula & Theory - Pressure Converter
The Pressure Converter uses pascal as the canonical SI unit:
Pa = value × factor(from)
result = Pa / factor(to)| Unit | Pa per unit |
|---|---|
| Pascal (Pa) | 1 |
| Kilopascal (kPa) | 1000 |
| Megapascal (MPa) | 1 000 000 |
| Bar | 100 000 |
| Millibar (mbar) | 100 |
| Atmosphere (atm) | 101 325 |
| psi | 6894.757293168 |
| ksi | 6 894 757.29317 |
| mmHg | 133.322387415 |
| inHg | 3386.389 |
| Torr | 133.322368421 |
| kgf/cm² | 98 066.5 |
