About These Units
- Atmospheres (atm)
- The standard atmosphere, defined as exactly 101,325 Pa to represent typical sea-level air pressure. Chemists use it for gas laws and standard conditions, and divers use it to describe the pressure at depth.
- mmHg (mmHg)
- The pressure exerted by a 1 mm column of mercury, about 133.322 Pa. It is the standard unit for blood pressure readings such as 120/80, and it is almost the same as the torr used in vacuum work.
