What does kilogram-force per square meter measure?

It measures pressure as the force exerted by one kilogram-force uniformly distributed over one square meter.

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

Foot water (4°C) represents the hydrostatic pressure from a one-foot column of water at 4°C, commonly used for low-pressure and hydraulic head measurements.

Can this converter be used for high-pressure applications?

No, both units represent relatively low pressures. For high pressures, other units are more appropriate.

Tips & Best Practices

Confirm the context of pressure values when working with non-SI kilogram-force units from older sources.
Account for the water temperature of 4°C when interpreting foot water pressure to ensure consistency.
Use this tool only for relatively low-pressure measurements as both units describe low-pressure ranges.
Verify conversions when integrating with modern SI measurements for accurate analysis.

Limitations

Kilogram-force/square meter is a non-SI unit commonly found in older documents and requires context for proper interpretation.
Foot water (4°C) is based on water density at 4°C; changes in temperature or fluid density can influence results.
Both units describe comparatively low pressures and may not be suitable for high-pressure scenarios.
