Definition
A bar (symbol: bar) is a unit of pressure equal to 100,000 pascals or approximately 0.987 atmospheres. It is widely used in meteorology, engineering, and industrial applications for measuring atmospheric and gauge pressures.
History/Origin
The bar was introduced in the early 20th century as a metric unit of pressure, derived from the Greek word "baros" meaning weight. It became widely adopted in Europe and is still commonly used despite not being an SI unit.
Current Use
Bars are used in meteorology for atmospheric pressure measurements, in diving for water pressure calculations, in industrial processes for pressure monitoring, and in engineering for hydraulic and pneumatic system specifications.
