The kilopascal
The kilopascal (kPa) equals exactly 1,000 pascals. It is the standard pressure unit in modern meteorology, engineering specs outside the US, and most non-US tire-pressure recommendations.
Kilopascals to Bars Converter
1 kPa = 0.01 bar
1 kilopascal equals 0.01 bars. To convert kilopascals to bars, multiply the kilopascal value by 0.01. For quick reference: 1 kPa = 0.01 bar, 5 kPa = 0.05 bar, 10 kPa = 0.1 bar, 100 kPa = 1 bar.
Formula
Bars = Kilopascals × 0.01Quick

Frequently asked questions
- How many bars are in 1 kilopascal?
- 1 kilopascal equals 0.01 bars.
- How do I convert kilopascals to bars?
- Multiply the kilopascal value by 0.01. So x kPa × 0.01 = the equivalent in bar.
- What is 5 kilopascals in bars?
- 5 kilopascals equals 0.05 bars.
- What is 10 kilopascals in bars?
- 10 kilopascals equals 0.1 bars.
- What is 100 kilopascals in bars?
- 100 kilopascals equals 1 bars.
- How do I convert back from bars to kilopascals?
- Multiply the bar value by 100. For example, 1 bar = 100 kPa.
- Is the kilopascal bigger than the bar?
- No. 1 kilopascal is smaller than 1 bar. It takes 100 kilopascals to equal 1 bar.
- Are these conversion factors exact?
- Yes. The factor of 0.01 is derived directly from the SI definitions of kilopascal and bar.
About the kilopascal and the bar
The bar
The bar equals exactly 100,000 pascals — close to but not equal to standard atmospheric pressure (1 atm = 1.01325 bar). It is the working unit for compressed-air systems, pneumatic tools, dive computers, and weather pressure outside North America.
