What does gram-force per square centimeter measure?

It measures pressure as the force of one gram-force distributed over one square centimeter, based on gravitational force.

Why use foot water (4°C) as a pressure unit?

Foot water (4°C) expresses pressure as the hydrostatic pressure from a 1-foot column of water at 4 degrees Celsius, commonly used for low-pressure hydraulics.

Are there any factors affecting the conversion accuracy?

Yes, variations in local gravity affect gram-force/sq. centimeter, and changes in water temperature or purity affect the foot water unit's pressure equivalence.

Examples

5 gram-force/sq. centimeter equals 0.164046765 foot water (4°C) [ftAq]
10 gram-force/sq. centimeter equals 0.32809353 foot water (4°C) [ftAq]

Common Use Cases

Calibrating instruments that use legacy pressure units in laboratories
Converting pressure readings into hydraulic head values for pump and water system design
Understanding groundwater pressure or static head via water column equivalents
Interpreting manometer and gauge data in HVAC and fluid measurement applications

Tips & Best Practices

Ensure consistent reference temperature (4°C) when using foot water units for accurate comparison
Use this tool to translate legacy pressure units into relevant hydraulic head measures for practical engineering use
Be aware that local gravity variations may slightly affect gram-force/sq. centimeter readings
Confirm that the water used in measurements corresponds to pure water at 4°C for valid pressure equivalences

Limitations

Gram-force/sq. centimeter is a non-SI unit influenced by local gravitational changes
Foot water (4°C) assumes pure water at a fixed temperature, so variations affect pressure accuracy
Conversion accuracy depends on consistent temperature and unit definitions between gravitational and hydrostatic pressures
