Convert Kilopound-force feet to Pound-force inches
Convert Kilopound-force feet (kip·ft) to Pound-force inches (lbf·in) instantly and accurately.
Conversion Formula
lbf·in = kip·ft × 12000
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.
About Pound-force inches
The pound-force inch (lbf·in) equals ≈ 0.11299 N·m, the dominant US customary unit for motor and machinery documentation. Rockwell Automation, Parker Hannifin, and Allied Motion servo catalogs express stall and rated torques in lbf·in; US machine-tool spindles and conveyor drive gearboxes are also specified in lbf·in. Typical fractional-horsepower motor torques: 5-200 lbf·in. 1 lbf·in ≈ 0.11299 N·m = 16 ozf·in = 1/12 lbf·ft.
