Bar to Kilopascal Converter (bar to kPa)
1 bar equals 100 kilopascals — multiply the number of bar by 100 to convert. This is an exact, whole-number relationship because both units are defined in pascals.
The formula
To convert bar to kilopascals, multiply by 100:
kPa = bar × 100
For example, 10 bar × 100 = 1000 kPa. To reverse it, divide by 100 (or multiply by 0.01).

FAQ
How many kilopascals are in a bar?
Exactly 100 kPa. So 2 bar is 200 kPa and 10 bar is 1,000 kPa.
How do I convert kilopascals back to bar?
Divide by 100, or multiply by 0.01. So 250 kPa is 2.5 bar.
Is the conversion exact?
Yes. 1 bar is defined as exactly 100,000 pascals, which is exactly 100 kPa, so there is no rounding.
