Frequently asked questions
What is the source unit in this conversion?
The source unit is the torr (Torr). A torr is 1/760 standard atmosphere.
What is the destination unit in this conversion?
The destination unit is the inhg (inHg). Inches of mercury.
How do I convert torr to inhg?
Multiply the torr value by 0.03937. For example, 10 Torr × 0.03937 = 0.393701 inHg.
Is the torr to inhg 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 torr needs to be compared with, or reported in, inhg, such as in engineering specifications, weather readings, tire pressure, or industrial and scientific work.
Can I convert inhg back to torr?
Yes. Multiply the inhg value by 25.400006 to get torr.

About this conversion
This page converts torr (Torr) to inhg (inHg) within the pressure converter.
A torr is 1/760 standard atmosphere. Inches of mercury.
The formula is inhg = torr × 0.03937, 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.
