Convert Atmosphere to Torr

Input the number of atmospheres you want to convert to torr.

1 atm (atmospheres) = 760 Torr (torr)

How to Convert Atmospheres to Torr

The atmosphere and torr are both units of pressure. 1 atmosphere equals 760 torr. This means to convert atmospheres to torr, you multiply by 760.

Formula

torr = atmospheres × 760

Step-by-Step Example

Convert 5 atm to torr:

1
Convert 5 atm to torr

We need to convert atmospheres to torr

2
Apply the formula

Since 1 atm = 760 Torr, multiply by 760

5 × 760 = 3800

Answer

5 atm = 3800 Torr

About These Units

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.

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.
