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 Attopascal (aPa). Attopascal is 1e-18 pascal units.
How do I convert mmHg to Attopascal?
Multiply the mmHg value by 1.33322e+20. For example, 10 mmHg × 1.33322e+20 = 1.33322e+21 aPa.
Is the mmHg to Attopascal 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, Attopascal, such as in engineering, scientific, or industrial calculations.
Can I convert Attopascal back to mmHg?
Yes. Multiply the Attopascal value by 0 to get mmHg.

About this conversion
This page converts mmHg (mmHg) to Attopascal (aPa) within the engineering converter.
Millimeters of mercury at standard gravity. Attopascal is 1e-18 pascal units.
The formula is aPa = mmHg × 1.33322e+20, 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.
