FAQ
What is the conversion factor from MPa to cmH₂O?
1 MPa equals 10197.16 cmH₂O. To convert, multiply the value in megapascals by 10197.16.
How do I convert 1 MPa to cmH₂O?
1 MPa = 10197.2 cmH₂O. For any value, multiply by 10197.16.
How do I convert cmH₂O back to MPa?
Divide by the same factor — or equivalently, multiply by 9.80665e-5. So 1 cmH₂O = 9.80665e-5 MPa.
When would I need to convert megapascal to centimetre of water column?
Pressure conversions between MPa and cmH₂O 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).
