Converting from Inch-Pound Force (in lbf) to Foot-Poundal (ft pdl) | Torque

What is Inch-Pound Force (in lbf)

Inch-Pound Force (in lbf) is a unit used to measure torque or rotational force. It represents the amount of force exerted when one pound-force is applied at a distance of one inch from the axis of rotation.

What is Foot-Poundal (ft pdl)

Foot-Poundal (ft pdl) is another unit of torque. It is defined as the amount of force required to accelerate a one-pound mass at a rate of one foot per second squared when applied to the end of a lever arm one foot long.
