Formula

Formula
inH₂O = dyn/cm² × 0.0004014631

Multiply any value in dynes per square centimetre by 0.0004014631 to obtain the value in inches of water column (4 °C).

Worked example

Convert 1000 dyn/cm² to inH₂O.

  1. 01Start with 1000 dyn/cm².
  2. 02Multiply by the conversion factor: 1000 × 0.0004014631 = 0.401463 inH₂O.
Result1000 dyn/cm² = 0.401463 inH₂O

FAQ

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