Formula
mbar = MPa × 10000
Multiply any value in megapascals by 10000 to obtain the value in millibars.
Worked example
Convert 1 MPa to mbar.
- 01Start with 1 MPa.
- 02Multiply by the conversion factor: 1 × 10000 = 10000 mbar.
Result1 MPa = 10000 mbar

FAQ
What is the conversion factor from MPa to mbar?
1 MPa equals 10000 mbar. To convert, multiply the value in megapascals by 10000.
How do I convert 1 MPa to mbar?
1 MPa = 10000 mbar. For any value, multiply by 10000.
How do I convert mbar back to MPa?
Divide by the same factor — or equivalently, multiply by 0.0001. So 1 mbar = 0.0001 MPa.
When would I need to convert megapascal to millibar?
Pressure conversions between MPa and mbar are common when working with mixed-vendor instrumentation, when piping codes use different units to process datasheets, or when converting field readings into SI for hydraulic calculations.
Is the conversion exact?
The factor shown is precise to at least 7 significant figures. For most process-engineering work this is far better than instrument accuracy. For metrology or trade applications, refer to the relevant national standard (NIST, BIPM, ISO 80000).
