What does 1 centimeter mercury (0°C) represent?

It represents the hydrostatic pressure exerted by a 1-centimetre column of mercury at 0 °C under standard gravity.

Why is foot water (4°C) used as a pressure unit?

Because it represents the hydrostatic pressure of a 1-foot column of pure water at 4°C, which is a common reference temperature for water density.

Can this conversion be used for dynamic fluid pressures?

No, this conversion is valid only for hydrostatic pressures, not for dynamic flows.
