Convert Kilonewton metres to Pound-force inches
Convert Kilonewton metres (kN·m) to Pound-force inches (lbf·in) instantly and accurately.
Conversion Formula
lbf·in = kN·m × 8850.745791
About Kilonewton metres
The kilonewton metre (kN·m) equals 1000 N·m, the standard unit for structural and civil engineering bending moments and large-machine torques. Steel beam connection bolts, industrial gearbox output shafts, ship propeller shaft flanges, and large AC induction motor ratings are specified in kN·m. Wind turbine mainshaft torques reach 1-10 MN·m. 1 kN·m = 1000 N·m ≈ 737.6 lbf·ft ≈ 0.7376 kip·ft ≈ 102.0 kgf·m.
About Pound-force inches
The pound-force inch (lbf·in) equals ≈ 0.11299 N·m, the dominant US customary unit for motor and machinery documentation. Rockwell Automation, Parker Hannifin, and Allied Motion servo catalogs express stall and rated torques in lbf·in; US machine-tool spindles and conveyor drive gearboxes are also specified in lbf·in. Typical fractional-horsepower motor torques: 5-200 lbf·in. 1 lbf·in ≈ 0.11299 N·m = 16 ozf·in = 1/12 lbf·ft.
