Convert Ounce-force inches to Gram-force centimetres
Convert Ounce-force inches (ozf·in) to Gram-force centimetres (gf·cm) instantly and accurately.
Conversion Formula
gf·cm = ozf·in × 72.00778874
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 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.
