Convert Kilopascals to Bars
1 kilopascal is 0.01 bar. One kilopascal is exactly 0.01 bars.
One kilopascal is 0.01 bars. To convert kilopascals to bars, multiply by 0.01; to go the other way, divide by 0.01 or multiply by 100. The factor is exact rather than rounded: it follows from NIST Special Publication 811. A thousand pascals, and the unit metric tyre placards and weather stations use.

Factors are entered by hand from NIST Special Publication 811 rather than derived from a units library, so the ones that terminate are exact rather than rounded.
How do you convert kilopascals to bars?
- 1.Take the measurement in kilopascals.
- 2.Multiply by 0.01 — that is how many bars fit in one kilopascal.
- 3.To go back the other way, divide by 0.01, or multiply by 100.
Worked example: 25 kilopascals to bars
- Formula
- kPa × 0.01 = bar
- Arithmetic
- 25 × 0.01 = 0.25 bar
- Answer
- 25 kPa = 0.25 bar
The factor is exact, so this figure is exact too — only the display is rounded.

What is a kilopascal?
A thousand pascals, and the unit metric tyre placards and weather stations use. Atmospheric pressure at sea level is about 101 kPa.
What is a bar?
Exactly 100,000 pascals by definition, chosen because it sits within a per cent of atmospheric pressure at sea level. European tyre placards and dive computers use it.
How many bars are in a kilopascal?
One kilopascal is 0.01 bars, exactly. Going the other way, one bar is 100 kilopascals. Both figures come from the same defined relation rather than from a measurement, which is why they are the same today as they were in 1959.
