Frequently asked questions
What is the source unit in this conversion?
The source unit is the mmhg (mmHg). Millimeters of mercury at standard gravity.
What is the destination unit in this conversion?
The destination unit is the millipascal (mPa). Millipascal is 0.001000000000000000020816681712 pascal units.
How do I convert mmhg to millipascal?
Multiply the mmhg value by 133322.387415. For example, 10 mmHg × 133322.387415 = 1.333224e+06 mPa.
Is the mmhg to millipascal conversion exact?
Yes. Both units are defined as fixed multiples of the pascal, the SI-derived unit of pressure, so the conversion factor follows directly from those exact definitions rather than a measured approximation.
Where is this conversion commonly used?
It's used whenever a value expressed in mmhg needs to be compared with, or reported in, millipascal, such as in engineering specifications, weather readings, tire pressure, or industrial and scientific work.
Can I convert millipascal back to mmhg?
Yes. Multiply the millipascal value by 0.000008 to get mmhg.

About this conversion
This page converts mmhg (mmHg) to millipascal (mPa) within the pressure converter.
Millimeters of mercury at standard gravity. Millipascal is 0.001000000000000000020816681712 pascal units.
The formula is millipascal = mmhg × 133322.387415, based on each unit's fixed relationship to the pascal, the pressure converter's base unit.
The conversion is exact, since both units are tied to the pascal by a fixed numerical ratio rather than a measured or approximate value.
