Convert Ounce-force inches to Kilopound-force feet
Convert Ounce-force inches (ozf·in) to Kilopound-force feet (kip·ft) instantly and accurately.
Conversion Formula
kip·ft = ozf·in × 5.208333333e-6
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 Kilopound-force feet
The kilopound-force foot (kip·ft) equals ≈ 1355.82 N·m (1 kip = 1000 lbf), the standard bending-moment and torque unit in US structural and civil engineering. AISC steel connection design, ACI reinforced-concrete beam moment capacity, and US bridge analysis all state values in kip·ft. Seismic moment-frame connections in mid-rise buildings resist 500-50 000 kip·ft. 1 kip·ft = 1000 lbf·ft ≈ 1355.82 N·m ≈ 1.35582 kN·m.
