millibar to megapascal
Convert millibar (mbar) to megapascal (MPa). Use an editable pressure converter, conversion formula, and reference table.
1 mbar = 0.0001 MPa
Conversion formula
One millibar equals 0.0001 megapascal. Multiply your value in millibar by this factor to get megapascal. For the reverse conversion, divide by the same factor.
Worked example
To convert 5 millibar:5 × 0.0001 = 0.0005 MPa

About these measurements
Pressure is force per unit of area.
The base reference used here is the pascal. One millibar is 100 base units; one megapascal is 1,000,000 base units.
Important distinctions
Gauge and absolute pressures must not be mixed. This converts units without changing the reference pressure.
Precision
The converter uses stored conversion factors and floating-point arithmetic. Results display up to ten significant digits, switching to scientific notation for very small or large values. Keep the precision of your original measurement when reporting results.
Common questions
How do I convert mbar to MPa?
Multiply the quantity in mbar by 0.0001. You can also type the value into the converter above.
Can I reverse the conversion?
Yes. Use the swap button or open the megapascal to millibar converter.
