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

It represents the hydrostatic pressure exerted by a 1-foot column of pure water at 4°C.

Why use millipascal for pressure measurements?

Millipascal is used to measure very small pressure magnitudes common in precision instrumentation and microfluidics.

Can I convert foot water (4°C) to millipascal for fluids other than water?

No, foot water (4°C) specifically assumes pure water at 4°C, so conversion for other fluids is not accurate.
