How to convert bar to kilopascals

kPa = bar × 100

Example: convert 8 bar to kilopascals.
8 bar × 100 = 800 kPa

The same relationship in reverse: 1 kilopascal = 0.01 bar, so you can also divide by 0.01. Need the other direction? Use the kilopascals to bar converter.

You will typically need this conversion for tire pressure stickers and plumbing.

About the units

Bar (bar)

Exactly 100,000 Pa, close to atmospheric pressure at sea level. Used for tires in Europe, espresso machines and diving.

Kilopascal (kPa)

1,000 Pa. Used for tire pressure in Canada, Australia and on many car door stickers.
