Atmospheres to Torr Conversion
Enter the pressure in atmospheres below to get the value converted to torr.
How to Convert Atmospheres to Torr

To convert an atmosphere measurement to a torr measurement, multiply the pressure by the conversion ratio. One atmosphere is equal to 760 torr, so use this simple formula to convert:
The pressure in torr is equal to the atmospheres multiplied by 760.
Atmospheres and torr are both units used to measure pressure. Keep reading to learn more about each unit of measure.
Atmospheres
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.
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.
