This converter turns bar into pascals instantly, using the exact factor 1 bar = 100000 pascals. 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 SI unit: one newton per square metre.
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
100000- The exact number of pascals in one bar
pascals- The converted result
How it works, step by step
- Enter the number of bar you want to convert.
- The value is multiplied by 100000, the exact conversion factor.
- The result is displayed in pascals, 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 100000. That gives 500,000 pascals. A quick sanity check: one bar is larger than one pascal, so the number should get bigger — and it does.
Converting 72 bar
72 × 100000 = 7,200,000 pascals. Working backwards, 7,200,000 ÷ 100000 returns 72 bar, which confirms the factor is applied the right way round.
How to read your score
Frequently asked questions
How many pascals are in one bar?
Exactly 100000. 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 pascals?
Pascals = bar × 100000. To reverse it, divide instead: bar = pascals ÷ 100000, which is the same as multiplying by 1e-05.
Is the bar bigger than the pascal?
Yes. One bar equals 100000 pascals, so it is the larger unit.
Why does my answer differ slightly from other bar to pascals 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.
