FAQ

What is the conversion factor from kgf/m² to inH₂O?
1 kgf/m² equals 0.03937008 inH₂O. To convert, multiply the value in kilograms-force per square metre by 0.03937008.
How do I convert 1 kgf/m² to inH₂O?
1 kgf/m² = 0.0393701 inH₂O. For any value, multiply by 0.03937008.
How do I convert inH₂O back to kgf/m²?
Divide by the same factor — or equivalently, multiply by 25.4. So 1 inH₂O = 25.4 kgf/m².
When would I need to convert kilogram-force per square metre to inch of water column (4 °C)?
Pressure conversions between kgf/m² 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).
