Conversion Formula
N·cm = ozf·in × 0.7061551814
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 Newton centimetres
The newton centimetre (N·cm) equals 0.01 N·m, a convenient unit for small-to-medium motors and robotics. Hobbyist robot joint actuators, prosthetic hand finger joints, and compact CubeSat reaction wheels are rated in N·cm. RC drone racing motors and small AC induction motors up to 100 W produce 5-200 N·cm. 1 N·cm = 0.01 N·m = 10 N·mm ≈ 1.416 ozf·in ≈ 0.0885 lbf·in.
