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 kilonewton-meter (kN·m) equals 1,000 N·m. Used for heavy machinery, large industrial motors, and structural engineering — the everyday unit becomes unwieldy past about 10⁴ N·m.
