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

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

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

Converting allows comparison of very small hydrostatic pressures to very high pressures used in fields like materials science and geophysics.

Is the converted value easy to interpret?

Due to the big difference in scale, converted values are extremely small and often require scientific notation for clarity.
