mbar to MPa Converter

How to convert millibars to megapascals

FormulaMPa = mbar × 0.0001

Multiply the value in millibars by 0.0001. To go the other way, multiply by 10,000 (or divide by 0.0001).

A millibar is smaller than a megapascal: it takes 10,000 millibars to make one megapascal.

About the units

Millibar (mbar)

The millibar (mbar) is a unit of pressure in the metric system. One millibar equals 100 pascals (Pa).

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 millibar?

There are 0.0001 megapascals in one millibar, and this value is exact by definition.

How do I convert millibars to megapascals?

Multiply the number of millibars by 0.0001. For example, 10 mbar × 0.0001 = 0.001 MPa.

How many millibars are in one megapascal?

One megapascal equals 10,000 millibars. That is the reverse factor, 1 ÷ 0.0001.

What is 10 millibars in megapascals?

10 mbar = 0.001 MPa.

Is this mbar 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.
