What is a millimeter water (4°C)?

It is the hydrostatic pressure from a 1 mm column of pure water at 4 °C under standard gravity, used for measuring very small pressures.

What does kilogram-force per square millimeter measure?

It is a gravitational unit of pressure or stress representing one kilogram-force applied to an area of one square millimeter.

When should I convert millimeter water (4°C) to kilogram-force/sq. millimeter?

When you need to express very small hydrostatic pressures in mechanical stress units for materials testing or engineering purposes.
