Torr to Millimeters of Mercury (Torr to mmHg) Converter
1 torr (Torr) = 1 millimeters of mercury (mmHg). To convert torr to millimeters of mercury, multiply by 1: 25 Torr × 1 = 25 mmHg. Also searched as torr to millimetres of mercury.
Quick facts
- 1 Torr = 1 mmHg
- 1 mmHg = 1 Torr
- Formula: mmHg = Torr × 1
- Quick estimate: multiply by about 1
How to convert torr to millimeters of mercury
- Take the value in torr.
- Multiply it by 1 (the number of millimeters of mercury in one torr).
- Round the result to the precision you need.
Worked example: 25 Torr × 1 = 25 mmHg.
To convert millimeters of mercury back to torr, multiply by 1, or divide by 1.
