bar to MPa Converter

How to convert bars to megapascals

FormulaMPa = bar × 0.1

Multiply the value in bars by 0.1. To go the other way, multiply by 10 (or divide by 0.1).

A bar is smaller than a megapascal: it takes 10 bars to make one megapascal.

About the units

Bar (bar)

Exactly 100,000 Pa, very close to one atmosphere. Common for tyres, scuba tanks and espresso machines (9 bar).

Megapascal (MPa)

One million pascals, equal to 1 N/mm². Concrete and steel strengths are given in MPa. One megapascal equals 1,000,000 pascals (Pa).

Frequently asked questions

How many megapascals are in one bar?

There are 0.1 megapascals in one bar, and this value is exact by definition.

How do I convert bars to megapascals?

Multiply the number of bars by 0.1. For example, 10 bar × 0.1 = 1 MPa.

How many bars are in one megapascal?

One megapascal equals 10 bars. That is the reverse factor, 1 ÷ 0.1.

What is 10 bars in megapascals?

10 bar = 1 MPa.

Is this bar to MPa converter accurate?

Yes. Both units are defined exactly in terms of SI units, so the conversion factor is exact; results are shown to 12 significant figures by default and you can change precision in the converter. Calculations run in your browser using the same tested engine that generated this page.
