Torr to Millimeters Of Mercury Converter
How to convert torr to millimeters of mercury
millimeters of mercury = torr ÷ 1.00000014
To convert torr to millimeters of mercury, divide the number of torr by 1.00000014.
1 Torr = 0.999999858 mmHg
Examples
- One standard atmosphere: 760 Torr ÷ 1.00000014 = 759.999892 mmHg
- 1 Torr ÷ 1.00000014 = 0.999999858 mmHg
Good to know
The two are equal for all practical purposes. The torr is 1/760 of a standard atmosphere and the conventional millimeter of mercury is 133.322387415 Pa, a difference of less than one part in seven million.
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 millimeter of mercury, 133.322387415 Pa. It differs from the torr (101,325/760 Pa) by less than one part in seven million, so the two are interchangeable in practice.

Unit definitions
- Torr
- A torr is exactly 1/760 of a standard atmosphere, about 133.322 pascals. It is used mainly for vacuum measurements.
- Millimeter of mercury (mmHg)
- A millimeter of mercury is the pressure exerted by a 1 mm column of mercury, conventionally 133.322387415 pascals. It is the standard unit for blood pressure readings.
