Pascal to PSI: values and formula

1 Pascal = 0.0001450377 PSI, and 1 PSI = 6894.76 Pascal. To convert a pressure value from Pascal to PSI, multiply it by 0.0001450377. For example, 10 Pascal equals 0.0014503768 PSI, and 250 Pascal equals 0.0362594202 PSI.

When to use the Pascal to PSI 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.
