FAQ

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