How to convert torr to pascal (pa)
Pressure is force per unit area. Pascals (and kPa, hPa) are SI, while bar and psi are widely used in engineering and scuba. Conversions must respect absolute vs gauge references when comparing values.
This converter calculates Torr to Pascal (Pa) values by using the correct conversion rule for the Pressure category. For linear units, standardized factors are used. For temperature, the calculator applies the proper formula with offsets.

Conversion formula
Linear unit conversions use standardized factors; many are exact by definition (e.g., 1 in = 25.4 mm, 1 ft = 0.3048 m).
Common mistakes
- Comparing gauge pressure (psig) with absolute pressure (psia/hPa) without converting reference.
- Mixing bar with atm (1 atm = 1.01325 bar).
Unit facts
- Torr: Torr is ≈133.322368 Pa; named after Torricelli (barometer). Used in vacuum science.
- Pascal (Pa): Pascal (Pa) is the SI unit of pressure: 1 Pa = 1 N/m².
About Torr
Torr
≈133.322 Pa. Preferred in high-vacuum work alongside millitorr and microns.
History: Named after Torricelli; bridges historical millimeters of mercury (mmHg) with SI pascals.
About Pascal (Pa)
Pascal (Pa)
SI unit equal to 1 N/m². Used for stress, tire pressure (kPa), and atmospheric science (hPa).
History: Named after Blaise Pascal; became practical with digital sensors capable of stable low-pressure readings.
