Factor1 hPa = 0.0001 MPa
Converter
hPa
Accepts numbers or expressions, e.g. 150 + 14.7
Result
MPa
Rendered to 6 significant figures.
Formula
Formula
MPa = hPa × 0.0001
Multiply any value in hectopascals by 0.0001 to obtain the value in megapascals.
Worked example
Convert 10000 hPa to MPa.
- 01Start with 10000 hPa.
- 02Multiply by the conversion factor: 10000 × 0.0001 = 1 MPa.
Result10000 hPa = 1 MPa

FAQ
What is the conversion factor from hPa to MPa?
1 hPa equals 0.0001 MPa. To convert, multiply the value in hectopascals by 0.0001.
How do I convert 1 hPa to MPa?
1 hPa = 0.0001 MPa. For any value, multiply by 0.0001.
How do I convert MPa back to hPa?
Divide by the same factor — or equivalently, multiply by 10000. So 1 MPa = 10000 hPa.
When would I need to convert hectopascal to megapascal?
Pressure conversions between hPa and MPa 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).
