lbf から mN 変換ツール - ポンド力 から ミリニュートン

Conversion derivation

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

1. 1

   Rewrite lbf in the base unit

   $$1\mathrm{lbf}=4.448222\mathrm{N}$$
2. 2

   Rewrite mN in the base unit

   $$1\mathrm{mN}=0.001\mathrm{N}$$
3. 3

   Forward conversion

   $$\begin{array}{rl}1\mathrm{lbf}& =\frac{4.448222\cancel{\mathrm{N}}}{0.001\cancel{\mathrm{N}}}\times 1\mathrm{mN}\\ & =\frac{4.448222}{0.001}\mathrm{mN}\\ & =4,448.222\mathrm{mN}\end{array}$$
4. 4

   Reverse conversion

   $$\begin{array}{rl}1\mathrm{mN}& =\frac{0.001\cancel{\mathrm{N}}}{4.448222\cancel{\mathrm{N}}}\times 1\mathrm{lbf}\\ & =\frac{0.001}{4.448222}\mathrm{lbf}\\ & =0.000224808924\mathrm{lbf}\end{array}$$
