# Standard atmospheres to torrs

**1 standard atmosphere in torrs: 1 atm = 760 Torr**

Torr = atm × 760

To convert standard atmospheres to torrs, multiply by 760. The table below gives the values people look up most often, and the converter works for any number.

## How the conversion works

The relationship is Torr = atm × 760. Both units measure pressure, so the conversion is a fixed factor that never changes.

## Common questions

### How many torrs are in one standard atmosphere?

One standard atmosphere equals 760 torrs. Torr = atm × 760.

### How do you convert standard atmospheres to torrs?

Use Torr = atm × 760. So 10 atm is 7,600 Torr.

### How many standard atmospheres are in one torr?

One torr equals 0.0013158 standard atmospheres, which is the reverse of the conversion above.
