What Is a Torr?

A torr is a unit used to measure pressure.

The torr is a non-SI metric unit for pressure. Torr can be abbreviated as Torr; for example, 1 torr can be written as 1 Torr.

Background and Origin

Originally the torr was defined as being equal to one millimeter of mercury. The torr was named for Italian physicist Evangelista Torricelli to recognize his invention of the barometer.

How Much Is a Torr?

The torr is a measure of pressure equal to 1/760 of an atmosphere. Torr is based on an absolute scale of pressure, which is equivalent to the atmospheric pressure plus the gauge pressure.

How to Convert Torr

To convert torr to another unit of pressure, you need to multiply the value by a conversion factor. A conversion factor is a numerical value used to change the units of a measurement without changing the value.^[1]

You can find the conversion factors for torr in the conversion table below.

Then, multiply the pressure measurement by the conversion factor to find the equivalent value in the desired unit of measurement.

torr × conversion factor = result

You can also use a calculator, such as one of the converters below, for the conversion.
