About the pound-foot and the pound-inch

The pound-foot

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 pound-inch

The pound-inch equals 1/12 of a pound-foot, or about 0.113 N·m. Used for fine-fastener torque specs (small bolts, screws) where pound-feet would produce inconveniently small numbers.
