Inches Of Mercury to Torr Converter
How to convert inches of mercury to torr
torr = inches of mercury × 25.4000036
To convert inches of mercury to torr, multiply the number of inches of mercury by 25.4000036.
1 inHg = 25.4000036 Torr
Examples
- Standard sea-level atmospheric pressure, as used for altimeter settings: 29.92 inHg × 25.4000036 = 759.968108 Torr
- 30 inHg × 25.4000036 = 762.000109 Torr
Good to know
This is the conventional inch of mercury, about 3386.389 Pa. Values defined at a specific mercury temperature differ slightly, for example 3376.85 Pa at 60 °F.
The torr is defined as 101,325/760 Pa. It differs from the millimeter of mercury (133.322387415 Pa) by less than one part in seven million.

Unit definitions
- Inch of mercury (inHg)
- An inch of mercury is the pressure exerted by a 1 inch column of mercury, conventionally about 3386.389 pascals. It is used in the United States for barometric pressure in weather reports and aviation.
- Torr
- A torr is exactly 1/760 of a standard atmosphere, about 133.322 pascals. It is used mainly for vacuum measurements.
