Question
Convert the following into basic units:
25365mg

Answer

$1 \mathrm{mg}=10^{-3} \mathrm{~g}$
$25365 \mathrm{mg}=2.5365 \times 10^4 \times 10^{-3} \mathrm{~g}$
$\text { Now, }$
$1 \mathrm{~g}=10^{-3} \mathrm{~kg}$
$2.5365 \times 10 \mathrm{~g}=2.5365 \times 10 \times 10^{-3} \mathrm{~kg}$
$\therefore 25365 \mathrm{mg}=2.5365 \times 10^{-2} \mathrm{~kg}$
