Understanding the Units

What is a Torr?

One torr equals exactly 1/760 of a standard atmosphere, or about 133.322 pascals — close to one millimeter of mercury.

Named after Evangelista Torricelli (1608–1647), inventor of the barometer.

Common contexts: vacuum technology, medical blood pressure.

What is an Atmosphere?

A standard atmosphere equals exactly 101,325 pascals — defined as the average atmospheric pressure at sea level.

Common contexts: chemistry, reference conditions.
