The bar is a widely used metric unit of measurement for pressure and 1 bar equals precisely 100,000 Pascals. Even though Bar is not an SI unit it has been adopted as one of the most popular pressure units particularly in European countries where most pressure measurement instruments are specified with pressure ranges in bar.

The value of 1 bar is a close approximation to atmospheric pressure and is often used to represent atmospheric pressure rather than standard atmosphere (101325 Pascals) which is the correct value used by the scientific and engineering community.

Use the following conversion factors to convert from Bar to other pressure units or vice versa. To convert a reading in Bar to another unit, multiply it by the relevant pressure conversion factor. To convert a reading in any pressure unit to Bar divide it by the relevant pressure conversion factor.

Alternatively convert from a bar pressure value into another unit using the bar conversion table or the pressure unit converter.
