About These Units
Pound-force Foot (lb·ft)
The pound-foot (lb·ft or ft·lb) is the standard US automotive torque unit. Often written as lb-ft, lb·ft, or foot-pounds. Typical car: 150-350 lb·ft, muscle car: 400-600 lb·ft, diesel truck: 700-1,500 lb·ft. One lb·ft = 1.356 N·m.
Newton Meter (N·m)
The newton meter (N·m) is the SI unit of torque—rotational force times lever arm distance. Standard automotive torque unit worldwide. Typical car: 200-400 N·m, sports car: 500-700 N·m, diesel truck: 1,000-2,500 N·m. Formula: τ = F × r. One N·m = 0.738 lb·ft.
