Frequently asked questions
What is the source unit in this conversion?
The source unit is the inHg (inHg). Inches of mercury.
What is the destination unit in this conversion?
The destination unit is the Torr (Torr). A torr is 1/760 standard atmosphere.
How do I convert inHg to Torr?
Multiply the inHg value by 25.4. For example, 10 inHg × 25.4 = 254 Torr.
Is the inHg to Torr 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 inHg needs to be compared with, or reported in, Torr, such as in engineering, scientific, or industrial calculations.
Can I convert Torr back to inHg?
Yes. Multiply the Torr value by 0.0393701 to get inHg.

About this conversion
This page converts inHg (inHg) to Torr (Torr) within the engineering converter.
Inches of mercury. A torr is 1/760 standard atmosphere.
The formula is Torr = inHg × 25.4, 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.
