How to Convert Bar to Kilopascal

To convert from Bar (bar) to Kilopascal (kPa), multiply the value by 100.

Formula: kPa = bar × 100

Reverse: bar = kPa × 0.01

Step-by-Step Example

Start with your value in Bar. For example: 5 bar
Multiply by the conversion factor: 5 x 100
The result is: 500 kPa

About Bar

The bar is a metric unit of pressure equal to 100,000 Pascals, roughly equal to atmospheric pressure at sea level.

Common uses: tire pressure, industrial, meteorology.

About Kilopascal

The kilopascal (kPa) is a unit of pressure and stress. One kilopascal equals 1000 pascals. UnitConvertLab converts it against every other pressure unit using this exact definition, so results are reproducible to full double precision rather than rounded lookup tables.

Common uses: pressure calculations, engineering and science, education.
