What does ton-force (long)/square foot measure?

It measures pressure by applying one long ton-force over one square foot area, commonly used in older imperial engineering contexts.

Why convert ton-force (long)/square foot to foot water (4°C)?

This conversion helps translate heavy load pressures into hydraulic head measurements relevant for fluid systems and groundwater analysis.

Can this conversion be used for any water temperature?

No, it is based on water at 4°C, the standard reference temperature for water density; different temperatures may affect accuracy.

Tips & Best Practices

Verify the original data is in ton-force (long)/square foot before conversion.
Use the tool for translating older imperial pressure figures to modern fluid pressure units.
Account for water temperature variations if high precision in foot water pressure is needed.
Cross-check results when converting very high pressures to foot water units due to differing magnitude scales.

Limitations

Assumes pure water at 4°C for foot water pressure accuracy; deviations in water density affect results.
Ton-force (long)/square foot units are primarily from historical imperial contexts and may not align with current standards.
Foot water units represent low pressures, so conversions from large ton-force values may exceed typical hydraulic head ranges.
