FAQ

What is the conversion factor from ksi to cmH₂O?
1 ksi equals 70306.96 cmH₂O. To convert, multiply the value in kilopounds-force per square inch by 70306.96.
How do I convert 1 ksi to cmH₂O?
1 ksi = 70307 cmH₂O. For any value, multiply by 70306.96.
How do I convert cmH₂O back to ksi?
Divide by the same factor — or equivalently, multiply by 1.422334e-5. So 1 cmH₂O = 1.42233e-5 ksi.
When would I need to convert kilopound-force per square inch to centimetre of water column?
Pressure conversions between ksi and cmH₂O 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).
