newtons to pound ft
Pound-feet is how American spec sheets write torque. Feed this converter newton-meters — from an engine dyno chart or a fastener table — and it returns pound-ft exactly, working included.

The exact factor
1 N·m = 0.7375621493 lb·ft
Derived from the defined constants 1 lb = 0.45359237 kg and gₙ = 9.80665 m/s² — no measurement error, only display rounding.

lb·ft = N·m × 0.7375621493, exact. Handy anchors: 100 N·m = 73.76 lb·ft, 135.6 N·m = 100 lb·ft, 500 N·m = 368.78 lb·ft.
The reverse trip multiplies by 1.3558179 — worth remembering as “about 1.36” when reading US car reviews with a metric head.
Interpreting torque figures
Peak engine torque tells you pulling power at one rpm point; its converted value carries the same meaning. A US-quoted “400 lb·ft” diesel matches a European “542 N·m” brochure — same engine, two languages.
Gearing multiplies torque: 300 N·m (221.3 lb·ft) at the crank through a 4:1 first gear becomes 1,200 N·m (885.1 lb·ft) at the wheels, before losses.
