The foot-poundal (symbol: ft-pdl) is a unit of energy that is part of the foot-pound-second system of units, in Imperial units introduced in 1879, and is from the specialized subsystem of English Absolut (a coherent system). The foot-poundal is equal to 1/32.174049 that of the more commonly used foot-pound force.
