Definition: A foot-pound is a unit of torque (or energy) in the Imperial system, defined as the torque resulting from a force of one pound-force applied at a distance of one foot from the pivot point.
History/origin: Commonly used in the United States and other countries that use Imperial units, especially in engineering and automotive contexts.
Current use: Foot-pounds are widely used in mechanical and automotive engineering to measure torque.
Definition: A newton-meter is the SI unit of torque, defined as the torque resulting from a force of one newton applied at a distance of one meter from the pivot point.
History/origin: Adopted internationally with the SI system, named after Sir Isaac Newton.
Current use: Newton-meters are the standard unit for torque in most scientific and engineering disciplines worldwide.

1 foot-pound = 1.35582 newton-meters
1 newton-meter = 0.73756 foot-pounds
Example: convert 50 foot-pounds to newton-meters:
50 × 1.35582 = 67.791 newton-meters
