Atmospheres to Torrs Converter

Convert atmospheres (atm) to torrs (Torr). 1 standard atmosphere = 760 torrs (exact)

1 standard atmosphere = 760 torrs

How to convert atmospheres to torrs

FormulaTorr = atm × 760

Multiply the value in atmospheres by 760. To go the other way, multiply by 0.001315789474 (or divide by 760).

A standard atmosphere is larger than a torr: one standard atmosphere contains 760 torrs.

Worked examples

About the units

Standard atmosphere (atm)

Exactly 101,325 Pa — average sea-level air pressure.

Torr (Torr)

Exactly 1/760 of a standard atmosphere; used in vacuum technology. One torr equals 133.3223684 pascals (Pa).

Frequently asked questions

How many torrs are in one standard atmosphere?

There are 760 torrs in one standard atmosphere, and this value is exact by definition.

How do I convert atmospheres to torrs?

Multiply the number of atmospheres by 760. For example, 10 atm × 760 = 7,600 Torr.

How many atmospheres are in one torr?

One torr equals 0.001315789474 atmospheres. That is the reverse factor, 1 ÷ 760.

What is 10 atmospheres in torrs?

10 atm = 7,600 Torr.

Is this atm to Torr converter accurate?

Yes. Both units are defined exactly in terms of SI units, so the conversion factor is exact; results are shown to 12 significant figures by default and you can change precision in the converter. Calculations run in your browser using the same tested engine that generated this page.
