FAQ

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