1 kgf·m = 7.23301 lb-ft (kilogram-force-meter → pound-foot)
1 kgf·m = 7.23301 lb-ft
1 kilogram-force-meter equals 7.23301 pound-feet. To convert kilogram-force-meters to pound-feet, multiply the kilogram-force-meter value by 7.23301. For quick reference: 1 kgf·m = 7.23301 lb-ft, 5 kgf·m = 36.1651 lb-ft, 10 kgf·m = 72.3301 lb-ft, 100 kgf·m = 723.301 lb-ft.
Pound-feet = Kilogram-force-meters × 7.23301Kilogram-force-meters to pound-feet multiplies by 7.23301 — 9.80665 N·m per kgf·m divided by the exact 1.3558179483314 N·m per lb-ft. A 25 kgf·m axle-nut spec from an older Japanese service manual is 180.8 lb-ft on a US wrench. This conversion is a staple of classic-car restoration, where original documentation quotes kgf·m but available tools read lb-ft. The rough '×7' mental shortcut runs 3% low — enough to matter on critical suspension and driveline fasteners.
Classic Japanese motorcycle collectors convert this when a 1980s factory manual is the only torque reference available: an original 4.5 kgf·m swingarm-pivot spec is 32.55 lb-ft on a modern US-made click wrench, a conversion essential to restoration work since no updated pound-foot manual for these older models was ever officially published.

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.
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.
