N vers mN convertisseur - Newton vers Millinewton

Conversion derivation

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

1. 1

   Rewrite N in the base unit

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

   Rewrite mN in the base unit

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

   Forward conversion

   $$\begin{array}{rl}1\mathrm{N}& =\frac{1\cancel{\mathrm{N}}}{0.001\cancel{\mathrm{N}}}\times 1\mathrm{mN}\\ & =\frac{1}{0.001}\mathrm{mN}\\ & =1,000\mathrm{mN}\end{array}$$
4. 4

   Reverse conversion

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