How to Convert Torr to Atmospheres
To convert a measurement in torr to a measurement in atmospheres, divide 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:
atmospheres = torr ÷ 760
The pressure in atmospheres is equal to the pressure in torr divided by 760.
For example, here's how to convert 500 torr to atmospheres using the formula above.
atmospheres = (500 Torr ÷ 760) = 0.657895 atm
Torr and atmospheres are both units used to measure pressure. Keep reading to learn more about each unit of measure.
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.

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.
