Atmospheres to Torr Converter
How to convert atmospheres to torr
torr = atmospheres × 760
To convert atmospheres to torr, multiply the number of atmospheres by 760.
1 atm = 760 Torr
Examples
- Standard sea-level atmospheric pressure: 1 atm × 760 = 760 Torr
- 2 atm × 760 = 1,520 Torr
Good to know
This is the standard atmosphere (atm), exactly 101,325 Pa. It is not the technical atmosphere (at), which is 1 kgf/cm² or 98,066.5 Pa.
The torr is defined as 101,325/760 Pa. It differs from the millimeter of mercury (133.322387415 Pa) by less than one part in seven million.

Unit definitions
- Atmosphere (atm)
- The standard atmosphere is defined as exactly 101,325 pascals, approximately the average air pressure at sea level. It is used as a reference pressure in chemistry and physics.
- Torr
- A torr is exactly 1/760 of a standard atmosphere, about 133.322 pascals. It is used mainly for vacuum measurements.
