kilopascal [kPa] to bar [bar] Converter

Quick Reference

1 kilopascal (kPa) = 0.01 bar (bar)

1 bar (bar) = 100 kilopascal (kPa)

How to Convert kilopascal to bar

1 kPa = 0.01 bar
1 bar = 100 kPa

To convert kilopascal to bar, divide the value by 100 (equivalently, multiply by 0.01). To convert bar back to kilopascal, multiply by 100.

Example: convert 10 kPa to bar:
10 kPa = 10 x 0.01 = 0.1 bar

↔ Convert bar to kilopascal

kilopascal

Definition: The kilopascal (symbol: kPa) is a multiple of the pascal, which is the SI unit of pressure and stress. One kPa is equal to 1000 pascals.

History/origin: Like the pascal, the kilopascal's origin is tied to the development of SI units. It provides a more convenient scale for expressing pressures larger than a single pascal.

Current use: Kilopascals are widely used in engineering, construction, and meteorology for measuring air pressure, fluid pressure, and mechanical stress.

bar

Definition: The bar (symbol: bar) is a metric unit of pressure, but not part of the International System of Units (SI). It is defined as exactly equal to 100,000 Pa (100 kPa), which is slightly less than current average atmospheric pressure on Earth at sea level.

History/origin: The bar was introduced by British meteorologist William Napier Shaw in 1909.

Current use: The bar is used in various fields, including meteorology, diving (for measuring pressure underwater), and industrial applications. It is often used when a unit close to atmospheric pressure is convenient.
