FAQ

What is the conversion factor from mH₂O to dyn/cm²?
1 mH₂O equals 98066.5 dyn/cm². To convert, multiply the value in metres of water column by 98066.5.
How do I convert 1 mH₂O to dyn/cm²?
1 mH₂O = 98066.5 dyn/cm². For any value, multiply by 98066.5.
How do I convert dyn/cm² back to mH₂O?
Divide by the same factor — or equivalently, multiply by 1.019716e-5. So 1 dyn/cm² = 1.01972e-5 mH₂O.
When would I need to convert metre of water column to dyne per square centimetre?
Pressure conversions between mH₂O and dyn/cm² 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).
