Convert Ounce-force inches to Gram-force metres
Convert Ounce-force inches (ozf·in) to Gram-force metres (gf·m) instantly and accurately.
Conversion Formula
gf·m = ozf·in × 0.7200778874
About Ounce-force inches
The ounce-force inch (ozf·in) equals ≈ 7.062 × 10⁻³ N·m, the traditional US unit for small instrument and servo motors. Brushless DC motors for drones, precision positioning stages, and US industrial servo catalogs (Maxon, Pittman) specify stall torque in ozf·in. A typical NEMA 17 stepper motor delivers 80-220 ozf·in. 16 ozf·in = 1 lbf·in. 1 ozf·in ≈ 7.062 × 10⁻³ N·m ≈ 72.0 gf·cm.
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.
