FAQ
What is the conversion factor from MPa to ftH₂O?
1 MPa equals 334.5526 ftH₂O. To convert, multiply the value in megapascals by 334.5526.
How do I convert 1 MPa to ftH₂O?
1 MPa = 334.553 ftH₂O. For any value, multiply by 334.5526.
How do I convert ftH₂O back to MPa?
Divide by the same factor — or equivalently, multiply by 0.002989067. So 1 ftH₂O = 0.00298907 MPa.
When would I need to convert megapascal to foot of water column (4 °C)?
Pressure conversions between MPa and ftH₂O 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).
