lbf vers kgf convertisseur - Force Livre vers Force Kilogramme

Conversion derivation

Express both lbf and kgf 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 kgf in the base unit

   $$1\mathrm{kgf}=9.80665\mathrm{N}$$
3. 3

   Forward conversion

   $$\begin{array}{rl}1\mathrm{lbf}& =\frac{4.448222\cancel{\mathrm{N}}}{9.80665\cancel{\mathrm{N}}}\times 1\mathrm{kgf}\\ & =\frac{4.448222}{9.80665}\mathrm{kgf}\\ & =0.453592409233\mathrm{kgf}\end{array}$$
4. 4

   Reverse conversion

   $$\begin{array}{rl}1\mathrm{kgf}& =\frac{9.80665\cancel{\mathrm{N}}}{4.448222\cancel{\mathrm{N}}}\times 1\mathrm{lbf}\\ & =\frac{9.80665}{4.448222}\mathrm{lbf}\\ & =2.20462243116\mathrm{lbf}\end{array}$$
