History & Background
The concept of torque is closely related to the lever principle; Archimedes famously said, "Give me a place to stand, and I will move the Earth." James Watt used pound-force feet to measure the output of steam engine shafts.
Conversion Details
Torque is the tendency of a force to rotate an object. The SI unit is the Newton-meter (N·m).
Common conversions: 1 lb·ft ≈ 1.3558 N·m, 1 kgf·m = 9.80665 N·m.
