lbf vers N convertisseur - Force Livre vers Newton

Conversion derivation

Express both lbf and N 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 N in the base unit

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

   Forward conversion

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

   Reverse conversion

   $$\begin{array}{rl}1\mathrm{N}& =\frac{1\cancel{\mathrm{N}}}{4.448222\cancel{\mathrm{N}}}\times 1\mathrm{lbf}\\ & =\frac{1}{4.448222}\mathrm{lbf}\\ & =0.224808923655\mathrm{lbf}\end{array}$$
