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 a Bar?

One bar equals exactly 100,000 pascals, very close to standard atmospheric pressure at sea level (about 1.01325 bar).

Common contexts: meteorology, industrial pressure.
