What does one kilonewton per square meter represent?

It is an SI unit of pressure equal to the force of one kilonewton applied over an area of one square meter, equivalent to 1,000 pascals.

Why is millimeter water (4°C) used for pressure measurements?

It represents the hydrostatic pressure from a 1 mm column of water at 4 °C, used mainly for measuring very small pressures in lab and low-pressure environments.

Can this conversion be used for all pressure ranges?

Although applicable, conversions from large units to very small units may produce large numbers that might not be practical for very high pressures.
