What does one millimeter water (4°C) represent?

It is the hydrostatic pressure exerted by a 1 mm column of pure water at 4°C under standard gravity, used for very small pressure measurements.

Why convert millimeter water (4°C) to megapascal?

This allows translating small hydrostatic pressures into a standard unit widely used in engineering and material strength calculations, facilitating interoperability.

Can this conversion be used for fluids other than water?

The unit is defined specifically for pure water at 4°C, so using it with other fluids or temperatures may reduce accuracy.
