Frequently asked questions
What is the source unit in this conversion?
The source unit is the hectopascal (hPa). Hectopascal is 100 pascal units.
What is the destination unit in this conversion?
The destination unit is the mmhg (mmHg). Millimeters of mercury at standard gravity.
How do I convert hectopascal to mmhg?
Multiply the hectopascal value by 0.750062. For example, 10 hPa × 0.750062 = 7.500616 mmHg.
Is the hectopascal to mmhg 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 hectopascal needs to be compared with, or reported in, mmhg, such as in engineering specifications, weather readings, tire pressure, or industrial and scientific work.
Can I convert mmhg back to hectopascal?
Yes. Multiply the mmhg value by 1.333224 to get hectopascal.

About this conversion
This page converts hectopascal (hPa) to mmhg (mmHg) within the pressure converter.
Hectopascal is 100 pascal units. Millimeters of mercury at standard gravity.
The formula is mmhg = hectopascal × 0.750062, 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.
Use the calculator above for instant results, or the table below for common hectopascal values already converted to mmhg.
