Convert Poundal feet to Ounce-force inches
Convert Poundal feet (pdl·ft) to Ounce-force inches (ozf·in) instantly and accurately.
Conversion Formula
ozf·in = pdl·ft × 5.967542433
About Poundal feet
The poundal foot (pdl·ft) equals ≈ 0.04214 N·m, the torque unit of the absolute foot-pound-second system, where force is in poundals (1 pdl = 1 lb·ft/s²) rather than pound-force. It appeared in pre-SI British and American engineering texts and NACA aerodynamic stability reports alongside slug inertia values. 1 pdl·ft = 0.45359237 × 0.3048² N·m ≈ 0.04214 N·m ≈ 0.3730 lbf·in.
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.
