Conversion Formula
lbf·in = gf·cm × 0.0008679616621
About Gram-force centimetres
The gram-force centimetre (gf·cm) equals 9.80665 × 10⁻⁵ N·m, the standard unit for small servo and hobby motor specifications. RC servo motor stall torques are quoted in gf·cm - a typical 9 g mini-servo delivers 1500-2000 gf·cm. Small stepper motors for 3D printers range 400-600 gf·cm; model train gearboxes around 200-800 gf·cm. 1 gf·cm = 9.80665 × 10⁻⁵ N·m = 10 gf·mm = 0.01 kgf·cm.
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.
