How to Convert Bar to Megapascal

To convert from Bar (bar) to Megapascal (MPa), multiply the value by 0.1.

Formula: MPa = bar × 0.1

Reverse: bar = MPa × 10

Step-by-Step Example

Start with your value in Bar. For example: 5 bar
Multiply by the conversion factor: 5 x 0.1
The result is: 0.5 MPa

About Bar

The bar is a metric unit of pressure equal to 100,000 Pascals, roughly equal to atmospheric pressure at sea level.

Common uses: tire pressure, industrial, meteorology.

About Megapascal

The megapascal (MPa) is a unit of pressure and stress. One megapascal equals 1.000000 × 10^+6 pascals. UnitConvertLab converts it against every other pressure unit using this exact definition, so results are reproducible to full double precision rather than rounded lookup tables.

Common uses: pressure calculations, engineering and science, education.
