A poundal is a unit of force in the foot–pound–second system, defined as the force that accelerates one pound-mass at one foot per second squared.

What does ton-force (long) represent?

Ton-force (long) is the force equal to the weight of one long ton (2240 pounds) under standard gravity, used historically in British engineering.

Why convert poundal to ton-force (long)?

This conversion is useful for interpreting or comparing small force values in FPS units with large legacy imperial forces used in naval and industrial settings.

Based on a fixed conversion rate between FPS and imperial legacy units
Useful for interpreting historical and legacy engineering data
Browser-based with an easy-to-use interface
Supports legacy measurement units relevant to classical mechanics and British industrial history

Examples

1000 poundal equals 0.0138754 ton-force (long)
500 poundal converts to 0.0069377 ton-force (long)

Common Use Cases

Converting forces expressed in FPS units to imperial forces used in older British machinery
Analyzing historical naval or shipbuilding documents referencing long ton-force
Interpreting and converting legacy engineering specifications for modern analysis
Educational problems involving classical mechanics using poundal units

Tips & Best Practices

Double-check unit selections before converting to ensure accurate results
Remember that poundal is a small force unit compared to ton-force (long)
Use this tool primarily for legacy data and historical engineering work
Be mindful of gravitational differences when comparing or converting forces
Avoid mixing different unit systems without understanding their context

Limitations

Converted values can be very small due to the size difference between units
Gravitational standards affect ton-force (long) measurements and must be considered
Less relevant for modern engineering where SI units are predominant
The tool does not support units outside the specified poundal and ton-force (long)
