1 bar equals 100 kilopascals. To convert bars to kilopascals, multiply the bar value by 100. For quick reference: 1 bar = 100 kPa, 5 bar = 500 kPa, 10 bar = 1000 kPa, 100 bar = 10000 kPa.
FormulaKilopascals = Bars × 100
Quick
When to use bars → kilopascals
Bar to kilopascals multiplies by 100 — 1 bar = 100 000 Pa = 100 kPa exactly. A 2.2 bar tyre is 220 kPa; a 6 bar espresso machine runs at 600 kPa (though good shots pull at ~9 bar = 900 kPa). Both are metric pressure units: the bar is convenient for round figures, the kilopascal is the SI-consistent choice. Australian tyre placards use kPa, continental European gauges use bar — this clean ×100 conversion bridges them.

Real-world reference
Standard atmospheric pressure is about 1.013 bar. A scuba tank is typically filled to 200 bar. In kilopascals, that gives you: 1 bar = 100 kPa, 10 bar = 1000 kPa, 100 bar = 10000 kPa.
Frequently asked questions
How many kilopascals are in 1 bar?
1 bar equals 100 kilopascals.
How do I convert bars to kilopascals?
Multiply the bar value by 100. So x bar × 100 = the equivalent in kPa.
What is 5 bars in kilopascals?
5 bars equals 500 kilopascals.
What is 10 bars in kilopascals?
10 bars equals 1000 kilopascals.
What is 100 bars in kilopascals?
100 bars equals 10000 kilopascals.
How do I convert back from kilopascals to bars?
Multiply the kilopascal value by 0.01. For example, 1 kPa = 0.01 bar.
Is the bar bigger than the kilopascal?
Yes. 1 bar is larger than 1 kilopascal — specifically 100 times larger.
Are these conversion factors exact?
Yes. The factor of 100 is derived directly from the SI definitions of bar and kilopascal.
About the bar and the kilopascal
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.
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.
