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