Torr to Inches Of Mercury Converter
How to convert torr to inches of mercury
inches of mercury = torr ÷ 25.4000036
To convert torr to inches of mercury, divide the number of torr by 25.4000036.
1 Torr = 0.0393700731 inHg
Examples
- One standard atmosphere: 760 Torr ÷ 25.4000036 = 29.9212556 inHg
- 1 Torr ÷ 25.4000036 = 0.0393700731 inHg
Good to know
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.
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.

Unit definitions
- Torr
- A torr is exactly 1/760 of a standard atmosphere, about 133.322 pascals. It is used mainly for vacuum measurements.
- 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.
