Convert Poundal feet to Kilopound-force feet
Convert Poundal feet (pdl·ft) to Kilopound-force feet (kip·ft) instantly and accurately.
Conversion Formula
kip·ft = pdl·ft × 3.108095017e-5
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 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.
