Bars to Kilopascals Converter

To convert a measurement in bars to kilopascals, multiply the value by 100. The conversion factor comes from the relationship between both units and the pascal.

For example, to convert 5 bar to kilopascals: 5 × 100 = 500 kPa.

A bar is a metric unit of pressure equal to exactly 100,000 pascals, roughly equal to atmospheric pressure at sea level. Introduced by Norwegian meteorologist Vilhelm Bjerknes, the bar takes its name from the Greek 'baros' (weight). Although not an SI unit, it remains popular in industry, diving, and weather because it is close to one atmosphere.

Common uses of bars include: Scuba diving depth and tank pressure; Industrial hydraulics and pneumatics; European tire and automotive pressure; Weather systems (via millibars).

A kilopascal equals 1,000 pascals and is the most common metric unit for everyday pressures such as tire inflation. The kilopascal became widespread as metric countries standardized on SI units, replacing older units like the kilogram-force per square centimeter in engineering and automotive specifications.

Common uses of kilopascals include: Tire pressure in metric countries; Blood pressure in some clinical contexts; HVAC and building pressure specifications; Compressed air and pneumatic systems.

Here are some common values converted:

1 bar = 100 kPa 5 bar = 500 kPa 10 bar = 1,000 kPa 50 bar = 5,000 kPa 100 bar = 10,000 kPa
