kN から lbf 変換ツール - キロニュートン から ポンド力

Conversion derivation

Express both kN and lbf in the same base unit N (newton), then cancel the shared base unit.

1. 1

   Rewrite kN in the base unit

   $$1\mathrm{kN}=1,000\mathrm{N}$$
2. 2

   Rewrite lbf in the base unit

   $$1\mathrm{lbf}=4.448222\mathrm{N}$$
3. 3

   Forward conversion

   $$\begin{array}{rl}1\mathrm{kN}& =\frac{1,000\cancel{\mathrm{N}}}{4.448222\cancel{\mathrm{N}}}\times 1\mathrm{lbf}\\ & =\frac{1,000}{4.448222}\mathrm{lbf}\\ & =224.808923655\mathrm{lbf}\end{array}$$
4. 4

   Reverse conversion

   $$\begin{array}{rl}1\mathrm{lbf}& =\frac{4.448222\cancel{\mathrm{N}}}{1,000\cancel{\mathrm{N}}}\times 1\mathrm{kN}\\ & =\frac{4.448222}{1,000}\mathrm{kN}\\ & =0.004448222\mathrm{kN}\end{array}$$
