lbf vers pN convertisseur - Force Livre vers Piconewton

Conversion derivation

Express both lbf and pN 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 pN in the base unit

   $$1\mathrm{pN}=1\times 10^{-12}\mathrm{N}$$
3. 3

   Forward conversion

   $$\begin{array}{rl}1\mathrm{lbf}& =\frac{4.448222\cancel{\mathrm{N}}}{1\times 10^{-12}\cancel{\mathrm{N}}}\times 1\mathrm{pN}\\ & =\frac{4.448222}{1\times 10^{-12}}\mathrm{pN}\\ & =4.448222\times 10^{12}\mathrm{pN}\end{array}$$
4. 4

   Reverse conversion

   $$\begin{array}{rl}1\mathrm{pN}& =\frac{1\times 10^{-12}\cancel{\mathrm{N}}}{4.448222\cancel{\mathrm{N}}}\times 1\mathrm{lbf}\\ & =\frac{1\times 10^{-12}}{4.448222}\mathrm{lbf}\\ & =2.24808924\times 10^{-13}\mathrm{lbf}\end{array}$$
