kJ vers MeV convertisseur - Kilojoule vers Méga Électron-Volt

Conversion derivation

Express both kJ and MeV in the same base unit J (joule), then cancel the shared base unit.

1. 1

   Rewrite kJ in the base unit

   $$1\mathrm{kJ}=1,000\mathrm{J}$$
2. 2

   Rewrite MeV in the base unit

   $$1\mathrm{MeV}=1.60217663\times 10^{-13}\mathrm{J}$$
3. 3

   Forward conversion

   $$\begin{array}{rl}1\mathrm{kJ}& =\frac{1,000\cancel{\mathrm{J}}}{1.60217663\times 10^{-13}\cancel{\mathrm{J}}}\times 1\mathrm{MeV}\\ & =\frac{1,000}{1.60217663\times 10^{-13}}\mathrm{MeV}\\ & =6.24150907\times 10^{15}\mathrm{MeV}\end{array}$$
4. 4

   Reverse conversion

   $$\begin{array}{rl}1\mathrm{MeV}& =\frac{1.60217663\times 10^{-13}\cancel{\mathrm{J}}}{1,000\cancel{\mathrm{J}}}\times 1\mathrm{kJ}\\ & =\frac{1.60217663\times 10^{-13}}{1,000}\mathrm{kJ}\\ & =1.60217663\times 10^{-16}\mathrm{kJ}\end{array}$$
