FAQ

What is the conversion factor from ftH₂O to dyn/cm²?
1 ftH₂O equals 29890.67 dyn/cm². To convert, multiply the value in feet of water column (4 °C) by 29890.67.
How do I convert 1 ftH₂O to dyn/cm²?
1 ftH₂O = 29890.7 dyn/cm². For any value, multiply by 29890.67.
How do I convert dyn/cm² back to ftH₂O?
Divide by the same factor — or equivalently, multiply by 3.345526e-5. So 1 dyn/cm² = 3.34553e-5 ftH₂O.
When would I need to convert foot of water column (4 °C) to dyne per square centimetre?
Pressure conversions between ftH₂O 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).
