Torr to Pascal: values and formula
1 Torr = 133.322 Pascal, and 1 Pascal = 0.0075006376 Torr. To convert a pressure value from Torr to Pascal, multiply it by 133.322. For example, 10 Torr equals 1333.22 Pascal, and 250 Torr equals 33330.5 Pascal.
| Torr | Pascal |

| 5 Torr | 666.61 Pascal |
| 10 Torr | 1333.22 Pascal |
| 25 Torr | 3333.05 Pascal |
| 50 Torr | 6666.1 Pascal |
| 100 Torr | 13332.2 Pascal |
| 500 Torr | 66661 Pascal |
| 1000 Torr | 133322 Pascal |
When to use the Torr to Pascal converter
- Tyre inflation — converting psi to bar and kPa.
- Weather forecasting — reading atmospheric pressure in hPa, mbar, or inHg.
- Industrial systems — specifying gauge and absolute pressure.
- Medical — reading blood pressure in mmHg.
A short history of pressure units
Pressure was first measured systematically by Torricelli in 1643 with the mercury barometer, giving rise to "torr" and "millimetres of mercury". The pascal (1 N/m²) became the SI unit. Atmospheric science uses bars and millibars, weather forecasting uses hPa, tyres use psi or bar, and meteorologists still quote inches of mercury in some regions.
Common mistakes when converting pressure
Gauge vs absolute pressure
"100 psi" usually means gauge pressure (above atmospheric). Absolute pressure adds about 14.7 psi.
Confusing bar and atm
1 bar is 100,000 Pa; 1 atm is 101,325 Pa. Close but not equal.
inHg unit ambiguity
Inches of mercury at 0°C and 60°F differ slightly — use 0°C (3386.39 Pa per inch) for scientific work.
