Convert Bars to Pascals
1 bar is 100,000 Pa. One bar is exactly 100000 pascals.
One bar is 100000 pascals. To convert bars to pascals, multiply by 100000; to go the other way, divide by 100000 or multiply by 1.0000 × 10^-5. The factor is exact rather than rounded: it follows from NIST Special Publication 811. Exactly 100,000 pascals by definition, chosen because it sits within a per cent of atmospheric pressure at sea level.

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 bars to pascals?
- 1.Take the measurement in bars.
- 2.Multiply by 100000 — that is how many pascals fit in one bar.
- 3.To go back the other way, divide by 100000, or multiply by 1.0000 × 10^-5.
Worked example: 25 bars to pascals
- Formula
- bar × 100000 = Pa
- Arithmetic
- 25 × 100000 = 2,500,000 Pa
- Answer
- 25 bar = 2,500,000 Pa
The factor is exact, so this figure is exact too — only the display is rounded.

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.
What is a pascal?
The SI unit: one newton spread over one square metre. It is a small pressure — a sheet of paper resting on a table is about one pascal — which is why the kilopascal is what instruments actually read.
How many pascals are in a bar?
One bar is 100000 pascals, exactly. Going the other way, one pascal is 1.0000 × 10^-5 bars. 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.

Questions people actually ask
- How many pascals are in a bar?
- 100000. The SI unit: one newton spread over one square metre. It is a small pressure — a sheet of paper resting on a table is about one pascal — which is why the kilopascal is what instruments actually read.
- How do I convert pascals back to bars?
- Divide by 100000, or multiply by 1.0000 × 10^-5 — they are the same operation.
