bar to Kilopascal

Exact answer: 1 bar = 100 kPa (exact – SI decimal prefix)

bar and Kilopascal both belong to the Pressure family. The difference is a decimal prefix, so the factor is a clean power of ten. Pressure appears in tyre data, weather reports, hydraulics, gas cylinders and vacuum technology.

Examples

010.1 bar = 10 kPa

Example value from the reference table. Internal calculation uses stored factors; display output is rounded.

02Common mistake

bar, psi and atm appear in different fields. Tyre, weather and lab values need context.

03Base unit: Pa

1 bar = 100000 Pa. Then the value is converted through the base unit Pa into Kilopascal.
