FAQ

What is the conversion factor from ksi to mH₂O?
1 ksi equals 703.0696 mH₂O. To convert, multiply the value in kilopounds-force per square inch by 703.0696.
How do I convert 1 ksi to mH₂O?
1 ksi = 703.07 mH₂O. For any value, multiply by 703.0696.
How do I convert mH₂O back to ksi?
Divide by the same factor — or equivalently, multiply by 0.001422334. So 1 mH₂O = 0.00142233 ksi.
When would I need to convert kilopound-force per square inch to metre of water column?
Pressure conversions between ksi and mH₂O 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).
