Convert Megapascals to Bars
1 megapascal is 10 bar. One megapascal is exactly 10 bars.
One megapascal is 10 bars. To convert megapascals to bars, multiply by 10; to go the other way, divide by 10 or multiply by 0.1. The factor is exact rather than rounded: it follows from NIST Special Publication 811. A million pascals.

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 megapascals to bars?
- 1.Take the measurement in megapascals.
- 2.Multiply by 10 — that is how many bars fit in one megapascal.
- 3.To go back the other way, divide by 10, or multiply by 0.1.
Worked example: 25 megapascals to bars
- Formula
- MPa × 10 = bar
- Arithmetic
- 25 × 10 = 250 bar
- Answer
- 25 MPa = 250 bar
The factor is exact, so this figure is exact too — only the display is rounded.

What is a megapascal?
A million pascals. Concrete strength and hydraulic ratings are specified here: 30 MPa concrete is about 4,350 psi.
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.
How many bars are in a megapascal?
One megapascal is 10 bars, exactly. Going the other way, one bar is 0.1 megapascals. 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.
