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 Atmosphere (atm). A standard atmosphere is exactly 101,325 pascals.
How do I convert mmHg to Atmosphere?
Multiply the mmHg value by 0.00131579. For example, 10 mmHg × 0.00131579 = 0.0131579 atm.
Is the mmHg to Atmosphere conversion exact?
Yes. Both units belong to the same engineering measurement family (pressure and mechanical stress), so the ratio between them is a fixed, defined value 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, Atmosphere, such as in engineering, scientific, or industrial calculations.
Can I convert Atmosphere back to mmHg?
Yes. Multiply the Atmosphere value by 760 to get mmHg.

About this conversion
This page converts mmHg (mmHg) to Atmosphere (atm) within the engineering converter.
Millimeters of mercury at standard gravity. A standard atmosphere is exactly 101,325 pascals.
The formula is atm = mmHg × 0.00131579, based on each unit's fixed relationship to the pressure and mechanical stress base unit.
The conversion is exact, since it relies on a fixed numerical ratio between the two units rather than a measured or approximate value.
