The pound-foot (lb-ft) is the customary torque unit in the United States. It equals exactly 1.355817948 N·m — derived from the pound-force (4.4482216152605 N) times the foot (0.3048 m). Often informally written 'ft-lb' or 'foot-pound', which technically denotes energy not torque, but the convention is universal in automotive spec sheets.
The kilogram-force-meter (kgf·m) equals 9.80665 N·m — one kilogram subjected to standard gravity, acting at a one-meter lever arm. Common in older European automotive documentation and in some industrial torque-wrench scales.
