Convert Torr to Atmosphere
Type the number of torr that you wish to convert to atmospheres.
How to Convert Torr to Atmospheres
The torr and atmosphere are both units of pressure. 1 atmosphere equals 760 torr. This means to convert torr to atmospheres, you divide by 760.
Formula
Step-by-Step Example
Convert 5 Torr to atmospheres:
We need to convert torr to atmospheres
Since 1 atm = 760 Torr, divide by 760
5 ÷ 760 = 0.0065789474
5 Torr = 0.0065789474 atm

About These Units
Torr (Torr)
A torr equals approximately 1 mmHg or 1/760 of an atmosphere. Torr measures vacuum pressure in scientific and industrial applications. Named after Italian physicist Evangelista Torricelli, inventor of the barometer. High vacuum is below 10⁻³ torr.
Atmosphere (atm)
One standard atmosphere (atm) equals 101,325 Pascals, 1.01325 bar, or 14.696 PSI—the average air pressure at sea level. Atmospheres measure diving depth (every 10 meters adds ~1 atm), altitude effects, and chemical reactions. Used as a reference pressure in science.
