Given, the mass of the matter$=1 \text{m}\text{g}=1\times {10}^{-6} \text{k}\text{g}$

As we know,$c=3\times {10}^8 {\text{m s}}^{-1}$

The matter will be converted into energy by the formula,$E=m{c}^2$

$=1\times {10}^{-6}\times {\left(3\times {10}^8\right)}^2$

$=1\times {10}^{-6}\times 9\times {10}^{16}$

$=9\times {10}^{\mathrm{10 }}\text{J}$
