Convert Ounce-force inches to Kilogram-force centimetres
Convert Ounce-force inches (ozf·in) to Kilogram-force centimetres (kgf·cm) instantly and accurately.
Conversion Formula
kgf·cm = ozf·in × 0.07200778874
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 Kilogram-force centimetres
The kilogram-force centimetre (kgf·cm) equals exactly 9.80665 × 10⁻² N·m, common in Continental European and Asian servo drive engineering. ABB, Siemens, and Yaskawa servo catalogs specify rotor and reflected-load torques in kgf·cm; IEC 61800 drive inertia-ratio sizing uses kgf·cm. Typical industrial servomotor stall torques: 0.1-50 kgf·cm. 1 kgf·cm = 0.0980665 N·m = 100 gf·cm ≈ 13.89 ozf·in.
