FAQ

What is the conversion factor from ftH₂O to kgf/m²?
1 ftH₂O equals 304.8 kgf/m². To convert, multiply the value in feet of water column (4 °C) by 304.8.
How do I convert 1 ftH₂O to kgf/m²?
1 ftH₂O = 304.8 kgf/m². For any value, multiply by 304.8.
How do I convert kgf/m² back to ftH₂O?
Divide by the same factor — or equivalently, multiply by 0.00328084. So 1 kgf/m² = 0.00328084 ftH₂O.
When would I need to convert foot of water column (4 °C) to kilogram-force per square metre?
Pressure conversions between ftH₂O and kgf/m² 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).
