How to convert torr to pascals
To convert a measurement in torr to pascals, multiply the value by 133.322368. The conversion factor comes from the relationship between both units and the pascal.
For example, to convert 5 Torr to pascals: 5 × 133.322368 = 666.611842 Pa.
What is a torr?
A torr is a unit of pressure defined as 1/760 of a standard atmosphere, approximately equal to one millimeter of mercury (about 133.32 pascals). Named after Evangelista Torricelli, inventor of the barometer, the torr is used mainly in vacuum technology and laboratory work where low pressures are measured against a mercury column.
Common uses of torr include: Vacuum system measurements; Laboratory and analytical instruments; Semiconductor process chambers; Physiology and respiratory gas pressures.
What is a pascal?
A pascal is the SI derived unit of pressure, equal to one newton of force per square meter (1 N/m²). Named after the French mathematician and physicist Blaise Pascal, the unit was adopted by the International System of Units in 1971. It is a small unit, so everyday pressures are usually expressed in kilopascals or bars.
Common uses of pascals include: Scientific and engineering stress calculations; Meteorological reporting (via hectopascals); Material strength and tensile testing; Fluid mechanics and aerodynamics.

Frequently asked questions
How many pascals are in one torr?
One torr (Torr) equals 133.322368 pascals (Pa). Multiply any value in torr by 133.322368 to convert to pascals.
How do I convert torr to pascals?
Multiply the value in torr by 133.322368. For example, 5 Torr × 133.322368 = 666.611842 Pa.
How do I convert pascals to torr?
Multiply the value in pascals by 0.007500616827, or divide by 133.322368. Use the swap button on the converter above to reverse the direction.
Is the torr to pascal conversion exact?
These conversions use standard SI-derived definitions. 1 atm = 101,325 Pa and 1 psi = 6,894.757 Pa exactly by definition.
What is the formula for torr to pascals?
The formula is: Pa = Torr × 133.322368. This comes from the definition of both units relative to the pascal.
