Frequently Asked Questions
-
What is a joule?
-
A joule is the SI derived unit of energy, defined as the work done when a force of one newton moves an object one meter, or equivalently, one watt-second.
-
What does poundal foot represent?
-
The poundal foot is an energy unit in the foot–pound–second system, representing work done by a force of one poundal acting through a displacement of one foot.
-
Why convert joules to poundal feet?
-
Conversion helps translate energy values from the modern SI system to FPS units used in classical mechanics problems and legacy engineering data.
Key Terminology
-
Joule [J]
-
The SI derived unit of energy representing one newton meter or one watt-second.
-
Poundal foot [pdl*ft]
-
A unit of energy in the FPS system equal to the work done by a one poundal force over one foot displacement.
-
FPS system
-
A system of measurement using foot, pound, and second as base units.
