kg vers u convertisseur - Kilogramme vers Unité de Masse Atomique

Conversion derivation

Express both kg and u in the same base unit kg (kilogram), then cancel the shared base unit.

1. 1

   Rewrite kg in the base unit

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

   Rewrite u in the base unit

   $$1\mathrm{u}=1.66053907\times 10^{-27}\mathrm{kg}$$
3. 3

   Forward conversion

   $$\begin{array}{rl}1\mathrm{kg}& =\frac{1\cancel{\mathrm{kg}}}{1.66053907\times 10^{-27}\cancel{\mathrm{kg}}}\times 1\mathrm{u}\\ & =\frac{1}{1.66053907\times 10^{-27}}\mathrm{u}\\ & =6.02214076\times 10^{26}\mathrm{u}\end{array}$$
4. 4

   Reverse conversion

   $$\begin{array}{rl}1\mathrm{u}& =\frac{1.66053907\times 10^{-27}\cancel{\mathrm{kg}}}{1\cancel{\mathrm{kg}}}\times 1\mathrm{kg}\\ & =\frac{1.66053907\times 10^{-27}}{1}\mathrm{kg}\\ & =1.66053907\times 10^{-27}\mathrm{kg}\end{array}$$
