Bar (unit symbol: bar) is a measuring unit for pressure. It is derived from Pascal (1 bar = 10 5 Pascal), which is used as a unit for pressure by the International System of Units (SI). The name is based on the ancient Greek word barýs (= heavy). 1 bar roughly equals the air pressure on the surface of the Earth.
