This converter turns bar into kilopascals instantly, using the exact factor 1 bar = 100 kilopascals. Type any number and the result updates as you go — nothing is sent to a server, so the arithmetic happens entirely in your browser.
Almost exactly atmospheric pressure; standard in European industry and diving. The standard tyre-pressure unit in metric countries.
Because the relationship is a simple proportion, one multiplication does the whole job. The table further down gives pre-computed values for the amounts people look up most often, and the result panel also reports the reverse conversion so you can check the figure both ways.
The formula
bar- The amount you are converting, measured in bar
100- The exact number of kilopascals in one bar
kilopascals- The converted result
How it works, step by step
- Enter the number of bar you want to convert.
- The value is multiplied by 100, the exact conversion factor.
- The result is displayed in kilopascals, rounded for readability.
- The unrounded value and the reverse conversion appear underneath so you can verify it.
Worked examples
Converting 5 bar
Multiply 5 by 100. That gives 500 kilopascals. A quick sanity check: one bar is larger than one kilopascal, so the number should get bigger — and it does.
Converting 72 bar
72 × 100 = 7,200 kilopascals. Working backwards, 7,200 ÷ 100 returns 72 bar, which confirms the factor is applied the right way round.
How to read your score
Frequently asked questions
How many kilopascals are in one bar?
Exactly 100. Every conversion on this page is that single number multiplied by your input, so the result carries no rounding error beyond what is shown.
What is the formula to convert bar to kilopascals?
Kilopascals = bar × 100. To reverse it, divide instead: bar = kilopascals ÷ 100, which is the same as multiplying by 0.01.
Is the bar bigger than the kilopascal?
Yes. One bar equals 100 kilopascals, so it is the larger unit.
Why does my answer differ slightly from other bar to kilopascals converters?
Most differences come from rounding the factor too early. This tool keeps full double precision through the calculation and only rounds at the final display step, and it also shows the unrounded value so you can see exactly where any difference appears.
