Convert Ounce-force inches to Kilogram-force metres
Convert Ounce-force inches (ozf·in) to Kilogram-force metres (kgf·m) instantly and accurately.
Conversion Formula
kgf·m = ozf·in × 0.0007200778874
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 metres
The kilogram-force metre (kgf·m) equals exactly 9.80665 N·m, used in pre-SI European and legacy Asian engineering. Soviet/Russian GOST standards, early JIS turbine and compressor specifications, and older DIN automotive standards listed torque in kgf·m. A car wheel bolt at 10 kgf·m ≈ 98.1 N·m. 1 kgf·m = 9.80665 N·m = 100 kgf·cm ≈ 7.233 lbf·ft ≈ 86.80 lbf·in.
