It is sometimes used as a reference pressure or standard pressure.
The standard atmosphere (symbol: atm) is a unit of pressure defined as 101325 Pa (1.01325 bar). The unit is named after Evangelista Torricelli, Italian physicist and mathematician, for his discovery of the principle of the barometer in 1643. It is the atmospheric pressure that supports a column of mercury 1 millimetre high. The torr (symbol: Torr) or millimetre of mercury (mmHg) is a non-SI unit of pressure.
