Definition
Meaning and Definition
A unit of work or energy in the foot-pound-second system, equal to the work done by a force of one poundal acting over a distance of one foot.
In engineering and physics, it represents a specific, small quantity of mechanical energy, often used in historical or theoretical contexts prior to the adoption of the SI system.
Dialectal Variation
British vs American Usage
Differences
No significant regional differences in meaning or usage, as it is a technical term. Both regions have largely superseded it with the joule.
Connotations
Historical, archaic, or highly specialized in both variants.
Frequency
Extremely rare in modern technical literature in both the UK and US. Slightly more likely to be encountered in older British engineering texts.

FAQ
Frequently Asked Questions
No, it is an obsolete unit from the foot-poundal-second (FPS) system, almost entirely replaced by the joule in the SI system.
A foot-pound (ft·lbf) is based on the gravitational pound-force, while a foot-poundal (ft·pdl) is based on the absolute poundal force. They measure the same thing (work/energy) but in different systems.
One foot-poundal is exactly equal to 0.0421401100938048 joules.
Only in historical scientific texts, some older engineering manuals, or academic discussions about the history of measurement systems.
A unit of work or energy in the foot-pound-second system, equal to the work done by a force of one poundal acting over a distance of one foot.
Foot-poundal is usually technical/scientific in register.
