FAQ

What is the conversion factor from inH₂O to dyn/cm²?
1 inH₂O equals 2490.889 dyn/cm². To convert, multiply the value in inches of water column (4 °C) by 2490.889.
How do I convert 1 inH₂O to dyn/cm²?
1 inH₂O = 2490.89 dyn/cm². For any value, multiply by 2490.889.
How do I convert dyn/cm² back to inH₂O?
Divide by the same factor — or equivalently, multiply by 0.0004014631. So 1 dyn/cm² = 0.000401463 inH₂O.
When would I need to convert inch of water column (4 °C) to dyne per square centimetre?
Pressure conversions between inH₂O 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).
