Are kilogram-force/square meter and millimeter water (4°C) exactly equal?

No, they measure related but not identical physical quantities, leading to small numerical differences in conversions.

Can I use this converter for high-pressure measurements?

This converter is intended for low-pressure contexts, and care should be taken when applying it outside such uses.

Tips & Best Practices

Ensure standard gravity conditions when interpreting converted values
Use the converter primarily for low-pressure measurements where millimeter water units are common
Apply conversions carefully in sensitive or regulatory contexts due to small numerical differences
Refer to original unit definitions when working with historical or legacy technical literature

Limitations

Small numerical differences exist since the units represent related but not identical physical quantities
Conversion is based on pure water at 4 °C and standard gravity; variations in environment may affect precision
Not suitable for contexts demanding exact pressure equivalence without considering subtle differences
