MJ in J Umrechner - Megajoule in Joule

Conversion derivation

Express both MJ and J 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 J in the base unit

   $$1\mathrm{J}=1\mathrm{J}$$
3. 3

   Forward conversion

   $$\begin{array}{rl}1\mathrm{MJ}& =\frac{1,000,000\cancel{\mathrm{J}}}{1\cancel{\mathrm{J}}}\times 1\mathrm{J}\\ & =\frac{1,000,000}{1}\mathrm{J}\\ & =1,000,000\mathrm{J}\end{array}$$
4. 4

   Reverse conversion

   $$\begin{array}{rl}1\mathrm{J}& =\frac{1\cancel{\mathrm{J}}}{1,000,000\cancel{\mathrm{J}}}\times 1\mathrm{MJ}\\ & =\frac{1}{1,000,000}\mathrm{MJ}\\ & =0.000001\mathrm{MJ}\end{array}$$
