What does a gram-force per square centimeter represent?

It is a unit of pressure based on the force of one gram-force applied evenly on an area of one square centimeter and is non-SI.

What is millimeter water (4°C) used for?

Millimeter water (4°C) measures very small hydrostatic pressures, especially in low-pressure environments like HVAC and laboratory settings.

Why is the conversion dependent on water temperature and gravity?

Because millimeter water (4°C) is defined by the pressure exerted by water at 4°C under standard gravity, variations affect measurement precision.
