What does foot water (4°C) represent?

It represents the hydrostatic pressure from a 1-foot column of pure water at 4°C, used for low pressure or hydraulic head measurements.

Why is newton per square meter used as a pressure unit?

It is the SI unit of pressure, quantifying force applied per area and widely used in scientific and engineering fields.

Can I use this conversion for water at other temperatures?

No, since the foot water unit is specific to water at 4°C, using other temperatures may introduce inaccuracies.
