FAQ

What is the conversion factor from ksi to ftH₂O?
1 ksi equals 2306.659 ftH₂O. To convert, multiply the value in kilopounds-force per square inch by 2306.659.
How do I convert 1 ksi to ftH₂O?
1 ksi = 2306.66 ftH₂O. For any value, multiply by 2306.659.
How do I convert ftH₂O back to ksi?
Divide by the same factor — or equivalently, multiply by 0.0004335275. So 1 ftH₂O = 0.000433528 ksi.
When would I need to convert kilopound-force per square inch to foot of water column (4 °C)?
Pressure conversions between ksi and ftH₂O 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).
