Convert Torr to Millimeter of Mercury
Convert torr to mmhg by entering a value below.
How to Convert Torr to mmHg
The torr and millimeter of mercury are both units of pressure. 1 millimeter of mercury equals 1.0000001425 torr. This means to convert torr to mmhg, you divide by 1.0000001425.
Formula
Step-by-Step Example
Convert 5 Torr to mmhg:
We need to convert torr to mmhg
Since 1 mmHg = 1.0000001425 Torr, divide by 1.0000001425
5 ÷ 1.0000001425 = 4.9999992877
5 Torr = 4.9999992877 mmHg

About These Units
Torr (Torr)
A torr equals approximately 1 mmHg or 1/760 of an atmosphere. Torr measures vacuum pressure in scientific and industrial applications. Named after Italian physicist Evangelista Torricelli, inventor of the barometer. High vacuum is below 10⁻³ torr.
Millimeter of Mercury (mmHg)
Millimeters of mercury (mmHg) measure blood pressure (normal: 120/80 mmHg), vacuum systems, and barometric pressure. Based on mercury column height in a manometer. Standard atmosphere equals 760 mmHg. Also called torr in scientific contexts.
