Convert Pound-force inches to Gram-force metres
Convert Pound-force inches (lbf·in) to Gram-force metres (gf·m) instantly and accurately.
Conversion Formula
gf·m = lbf·in × 11.5212462
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.
About Gram-force metres
The gram-force metre (gf·m) equals 9.80665 × 10⁻³ N·m, used in scientific torsion and balance instrument calibration. Analytical balance torsion spring constants, laser-gyroscope gimbal friction torques, and lightweight UAV propeller starting torques are expressed in gf·m. It bridges gf·cm and N·m in laboratory-scale rotating experiments. 1 gf·m = 9.80665 × 10⁻³ N·m = 100 gf·cm = 0.001 kgf·m.
