Pie/libra, libra/pie

Foot pounts (ft.lbs.), or pound feet (lb.ft.), is a unit of torque measurement – representing a point of force acting at a perpendicular distance of one foot from a pivot point.

Another common unit of torque measurement is newton meters. Here are the conversion formulas:

N-M = lb.ft. x 1.359

Lb.ft = (N-M) / 0.738
