Torr |

The **torr** (symbol: Torr) is a unit of pressure based on an absolute scale, now defined as exactly 1/760 of a standard atmosphere. Thus one torr is exactly 101325/760 pascal (~133.3 Pa).

Historically, one **torr** was intended to be the same as one **millimetre of mercury**. However, subsequent redefinitions of the two units made them slightly different (by less than 0.000015%).
