torr = mm Hg in a barometer or manometer

The pressure of air or a gas moves the column of Hg in the barometer or manometer. We measure the distance moved in mm, so we use the term "mm Hg" to express the pressure exerted by the air or other gas. The unit "mm Hg" is often replaced by "torr" to honor Torricelli.

torr is a measure of atmospheric pressure, and 1 torr equals the displacement of 1 mm of mercury in a barometer.
