How to Convert Torr to Millipascals

To convert torr to millipascals, multiply the pressure by the following conversion ratio: 133,322.3684211 millipascals/torr.

Since one torr is equal to 133,322.3684211 millipascals, you can use this simple formula to convert:

millipascals = torr × 133,322.3684211

The pressure in millipascals is equal to the pressure in torr multiplied by 133,322.3684211.

For example, here's how to convert 5 torr to millipascals using the formula above.

millipascals = (5 Torr × 133,322.3684211) = 666,611.8421053 mPa

How Many Millipascals Are in a Torr?

There are 133,322.3684211 millipascals in a torr, which is why we use this value in the formula above.

1 Torr = 133,322.3684211 mPa|1 mPa = 0.000007501 Torr

Our torr to millipascal calculator automatically converts your pressure measurements with full decimal and scientific precision across US customary, imperial, and SI metric standards.

Torr and millipascals 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 Millipascal?

A millipascal is a unit of pressure equal to 1/1,000 of a pascal (0.001 Pa). One-thousandth of a Pascal. [2]

The millipascal is classified as a metric and SI-compatible unit of pressure. Millipascals can be abbreviated as mPa; for example, 1 millipascal can be written as 1 mPa.

In the metric system, "milli" is the standard SI prefix for thousandths, or 10⁻³. This makes the millipascal (mPa) a convenient decimal multiple of the pascal (Pa).

In practice, millipascals (mPa) are widely used across fine-tolerance laboratory, analytical, and micro-scale pressure measurements within SI metric workflows, engineering documentation, and technical data sheets.

When converting pressure between torr (Torr) and millipascals (mPa), keep full floating-point precision (1 Torr = 133,322.3684211 mPa; 1 mPa = 0.000007501 Torr) during intermediate calculations and round only the final millipascal figure to match your instrument tolerance.
