Millimeters Of Mercury to Torr Converter
How to convert millimeters of mercury to torr
torr = millimeters of mercury × 1.00000014
To convert millimeters of mercury to torr, multiply the number of millimeters of mercury by 1.00000014.
1 mmHg = 1.00000014 Torr
Examples
- 120 mmHg × 1.00000014 = 120.000017 Torr
- Approximately standard atmospheric pressure: 760 mmHg × 1.00000014 = 760.000108 Torr
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.
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.
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
- 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.
- Torr
- A torr is exactly 1/760 of a standard atmosphere, about 133.322 pascals. It is used mainly for vacuum measurements.
