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 millibar (mbar). A millibar is 100 pascals.
How do I convert mmhg to millibar?
Multiply the mmhg value by 1.333224. For example, 10 mmHg × 1.333224 = 13.332239 mbar.
Is the mmhg to millibar 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, millibar, such as in engineering specifications, weather readings, tire pressure, or industrial and scientific work.
Can I convert millibar back to mmhg?
Yes. Multiply the millibar value by 0.750062 to get mmhg.

About this conversion
This page converts mmhg (mmHg) to millibar (mbar) within the pressure converter.
Millimeters of mercury at standard gravity. A millibar is 100 pascals.
The formula is millibar = mmhg × 1.333224, 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.
