How to Convert Pound-foot to Kilonewton-meter
- 1 lbf·ft = 0.001355817948 kN·m
- 1 kN·m = 737.5621493 lbf·ft
- Example: convert 15 lbf·ft to kN·m: 15 lbf·ft = 15 × 0.001355817948 kN·m = 0.02033726922 kN·m
Formula
kN·m = lbf·ft × 0.001355817948331
or kN·m = lbf·ft ÷ 737.5621492773
Derivation from SI units:
- 1 lbf·ft = 4.4482216152605 N × 0.3048 m = 1.3558179483314 N·m
- 1 kN·m = 10³ N·m
- 1 lbf·ft = 1.355817948331 N·m ÷ 1000 N·m per kN·m = 0.001355817948331 kN·m
Both units are defined exactly, so the factor is exact. Pound-foot definition: pound-foot; Kilonewton-meter definition: kilonewton-meter.
Worked examples
- A reading of 30 lbf·ft converts to 0.04067453845 kN·m.
30 lbf·ft × 0.001355817948 = 0.04067453845 kN·m - A value of 200 lbf·ft is 0.2711635897 kN·m.
200 lbf·ft × 0.001355817948 = 0.2711635897 kN·m
