What does foot water (4°C) represent?

It is a pressure unit equal to the hydrostatic pressure from a one-foot column of pure water at 4°C, commonly used for expressing low pressures or hydraulic head.

Where is ton-force (long)/square foot commonly used?

This unit is used to estimate foundation bearing pressure in older engineering documents and to specify load capacities in shipbuilding involving long tons.

Can this conversion be used for dynamic pressure measurements?

No, this conversion is valid only for static or hydrostatic pressure conditions and may not apply to dynamic or non-uniform loads.

Click the convert button to view the equivalent pressure in ton-force (long)/square foot.

Key Features

Converts low hydrostatic pressure units based on water column height into heavy-load pressure units.
Supports conversions relevant to civil engineering, shipbuilding, and legacy engineering documents.
Displays results using widely recognized imperial and historical pressure units.
Simple and quick to use with straightforward input and output formats.

Examples

Converting 10 foot water (4°C) results in 0.278688148 ton-force (long)/square foot.
50 foot water (4°C) converts to approximately 1.39344074 ton-force (long)/square foot.

Common Use Cases

Calculating foundation bearing pressure in vintage engineering documents using imperial units.
Determining deck or platform load capacity in shipbuilding with traditional measurement units.
Translating hydraulic pressure measurements into load-bearing capacities in structural engineering.
Converting historical pressure specifications into contemporary SI unit equivalents.

Tips & Best Practices

Ensure water temperature is 4°C for accurate foot water pressure measurements.
Consider additional unit conversions if working exclusively within the SI system.
Apply this conversion primarily for static and hydrostatic pressure conditions.

Limitations

The foot water (4°C) unit depends on pure water at 4°C, so changes in water conditions may reduce accuracy.
Ton-force (long)/square foot is based on imperial units involving the long ton, requiring caution when integrating with SI units.
This conversion applies only to static pressure scenarios, not dynamic or uneven load conditions.
