Frequently asked questions

What is the source unit in this conversion?

The source unit is the torr (Torr). A torr is 1/760 standard atmosphere.

What is the destination unit in this conversion?

The destination unit is the atmosphere (atm). A standard atmosphere is exactly 101,325 pascals.

How do I convert torr to atmosphere?

Multiply the torr value by 0.001316. For example, 10 Torr × 0.001316 = 0.013158 atm.

Is the torr to atmosphere conversion exact?

Yes. Both units are defined as fixed multiples of the pascal, the SI-derived unit of pressure, so the conversion factor follows directly from those exact definitions rather than a measured approximation.

Where is this conversion commonly used?

It's used whenever a value expressed in torr needs to be compared with, or reported in, atmosphere, such as in engineering specifications, weather readings, tire pressure, or industrial and scientific work.

Can I convert atmosphere back to torr?

Yes. Multiply the atmosphere value by 760 to get torr.

About this conversion

This page converts torr (Torr) to atmosphere (atm) within the pressure converter.

A torr is 1/760 standard atmosphere. A standard atmosphere is exactly 101,325 pascals.

The formula is atmosphere = torr × 0.001316, based on each unit's fixed relationship to the pascal, the pressure converter's base unit.

The conversion is exact, since both units are tied to the pascal by a fixed numerical ratio rather than a measured or approximate value.
