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

One foot water (4°C) is the pressure exerted by a column of pure water one foot high at 4°C, commonly used to indicate low pressures or hydraulic head.

Why use newton per square millimeter as a pressure unit?

Newton per square millimeter measures mechanical stress or pressure, ideal for expressing tensile, compressive strengths, and hydraulic pressures in engineering.

Can this conversion be used for fluids other than water?

No, this conversion specifically relates to pure water at 4°C and may not be accurate for other fluids or temperatures.
