MJ a MeV convertitore - Megajoule a Mega elettronvolt

Conversion derivation

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

1. 1

   Rewrite MJ in the base unit

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

   Rewrite MeV in the base unit

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

   Forward conversion

   $$\begin{array}{rl}1\mathrm{MJ}& =\frac{1,000,000\cancel{\mathrm{J}}}{1.60217663\times 10^{-13}\cancel{\mathrm{J}}}\times 1\mathrm{MeV}\\ & =\frac{1,000,000}{1.60217663\times 10^{-13}}\mathrm{MeV}\\ & =6.24150907\times 10^{18}\mathrm{MeV}\end{array}$$
4. 4

   Reverse conversion

   $$\begin{array}{rl}1\mathrm{MeV}& =\frac{1.60217663\times 10^{-13}\cancel{\mathrm{J}}}{1,000,000\cancel{\mathrm{J}}}\times 1\mathrm{MJ}\\ & =\frac{1.60217663\times 10^{-13}}{1,000,000}\mathrm{MJ}\\ & =1.60217663\times 10^{-19}\mathrm{MJ}\end{array}$$
