To convert a measurement in atmospheres to a measurement in torr, multiply the pressure by the following conversion ratio: 760 torr/atmosphere.

Since one atmosphere is equal to 760 torr, you can use this simple formula to convert:

torr = atmospheres × 760

The pressure in torr is equal to the pressure in atmospheres multiplied by 760.

For example, here's how to convert 5 atmospheres to torr using the formula above.
torr = (5 atm × 760) = 3,800 Torr

Atmospheres and torr are both units used to measure pressure. Keep reading to learn more about each unit of measure.

What Is an Atmosphere?

The atmosphere is a reference measure of pressure equal to 101,325 pascals or 1,013,250 dynes. The atmosphere was originally defined as the pressure of 760 millimeters of mercury at standard gravity at 0 °C, but was later redefined in 1954 to be equal to 1,013,250 dynes.

Atmospheres can be abbreviated as atm; for example, 1 atmosphere can be written as 1 atm.

What 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.

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.
