About Bending Moment Units
- Bending moment (M) represents the internal moment that resists bending in a structural member. In SI structural engineering, kN·m is the standard unit for beam moments, column base moments and foundation design.
- In US structural practice, the kip·ft (kip-foot) is dominant. 1 kip = 1,000 lbf ≈ 4.448 kN. Structural steel design codes (AISC) and concrete codes (ACI) express moment demands and capacities in kip·ft.
- lbf·ft is used in lighter-duty applications and mechanical engineering. For large structural calculations, lbf·ft values become very large numbers, so kip·ft is preferred for readability. 1 kip·ft = 1,000 lbf·ft.
- Quick reference: 1 kN·m = 1,000 N·m = 0.737562 kip·ft = 737.562 lbf·ft · 1 kip·ft = 1.35582 kN·m = 1,355.82 N·m = 1,000 lbf·ft.
