FAQ

What is the conversion factor from cmH₂O to dyn/cm²?
1 cmH₂O equals 980.665 dyn/cm². To convert, multiply the value in centimetres of water column by 980.665.
How do I convert 1 cmH₂O to dyn/cm²?
1 cmH₂O = 980.665 dyn/cm². For any value, multiply by 980.665.
How do I convert dyn/cm² back to cmH₂O?
Divide by the same factor — or equivalently, multiply by 0.001019716. So 1 dyn/cm² = 0.00101972 cmH₂O.
When would I need to convert centimetre of water column to dyne per square centimetre?
Pressure conversions between cmH₂O 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).
