What does foot water (4°C) measure?

Foot water (4°C) measures the hydrostatic pressure exerted by a 1-foot column of pure water at 4°C, used commonly for low pressure or hydraulic head representation.

Why use kilogram-force per square centimeter?

Kilogram-force per square centimeter is used in older or regional engineering contexts to rate hydraulic systems and equipment where non-SI units persist.

Is this converter suitable for all scientific calculations?

No, since kilogram-force per square centimeter is a non-SI unit and foot water (4°C) is specific to water at 4°C, this conversion may not be appropriate for all scientific applications.
