How to Convert Torr to Pascals
To convert torr to pascals, multiply the pressure by the following conversion ratio: 133.3223684 pascals/torr.
Since one torr is equal to 133.3223684 pascals, you can use this simple formula to convert:
The pressure in pascals is equal to the pressure in torr multiplied by 133.3223684.
For example, here's how to convert 5 torr to pascals using the formula above.
How Many Pascals Are in a Torr?
There are 133.3223684 pascals in a torr, which is why we use this value in the formula above.
Our torr to pascal calculator automatically converts your pressure measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.
Torr and pascals are both units used to measure pressure. Keep reading to learn more about each unit.
What Is a Torr?
A torr is a unit of pressure equal to 133.3223684 pascals (Pa), the base unit for pressure. 1/760 of a standard atmosphere (133.3224 Pascals). [1]
The torr is classified as a standard unit of pressure. Torr can be abbreviated as Torr; for example, 1 torr can be written as 1 Torr.
When working with torr (Torr) in formulas or technical specifications, always verify whether your target system uses SI metric, US customary, or British imperial standards.
In practice, torr (Torr) are widely used across standard pressure applications within international standard workflows, engineering documentation, and technical data sheets.
What Is a Pascal?
SI derived unit of pressure equal to 1 Newton per square meter (N/m²). It serves as a primary reference unit for measuring pressure across scientific and practical applications. [2]
The pascal is classified as an International System of Units (SI) unit of pressure. Pascals can be abbreviated as Pa; for example, 1 pascal can be written as 1 Pa.
As the primary coherent reference unit for pressure in this category, all other pressure units are mathematically anchored to the pascal (Pa).
In practice, pascals (Pa) are widely used across standard pressure applications within International System of Units (SI) workflows, engineering documentation, and technical data sheets.
When converting pressure between torr (Torr) and pascals (Pa), keep full floating-point precision (1 Torr = 133.3223684 Pa; 1 Pa = 0.0075006 Torr) during intermediate calculations and round only the final pascal figure to match your instrument tolerance.
