How to convert Bar to Kilopascals
1 bar equals 100 kPa. Use the converter above for any value, or read the table for common conversions.
kPa = bar × 100 · bar = kPa × 0.01Multiply a bar figure by 100 to get kilopascals, or divide it by 0.01 to go the other way.
Worked examples
- 1 bar= 100 kPa
- 2 bar= 200 kPa
- 5 bar= 500 kPa
- 10 bar= 1,000 kPa
- 50 bar= 5,000 kPa
What these units are
Bar (bar). One bar is exactly 100,000 pascals, slightly less than one atmosphere. It is used for tyre pressure, industrial gases and weather charts.
Kilopascals (kPa). A kilopascal is 1,000 pascals. It is the unit for tyre pressure in metric countries, and is used for gas and weather pressures.
Bar, atmosphere and psi are exact definitions. Gauges and weather stations round heavily, so treat the last digit as indicative rather than precise.
Checking a bar to kilopascals conversion
Pressure units are all defined against the pascal, so the conversion is a multiplication by a fixed number. What makes this dimension awkward is that the numbers sit within tens of per cent of each other, so a small slip looks plausible.
Three of the units are close together on purpose: one bar is 100,000 pascals, one atmosphere is 101,325, and weather reports use millibars and hectopascals, which are the same size. A reading that looks like a unit error is often a genuine difference between gauge pressure and absolute pressure instead.
Checking a pressure conversion means converting through pascals and comparing with a known reference, such as the fact that a bar and an atmosphere differ by about 1.3%. The error to watch for is quoting a pressure without saying whether it is measured above atmospheric pressure or from a vacuum.
