Question

Express as $\mathrm{kg}$ using decimal: $2\mathrm{g}$

Answer 1

Express as Kilogram:

Given mass: $2\mathrm{g}$.

It is known that, $1\mathrm{g}=\frac{1}{1000}\mathrm{kg}=0.001\mathrm{kg}$.

Thus, $2\mathrm{g}=\left(2\times 0.001\right)\mathrm{kg}=0.002\mathrm{kg}$.

Hence $2\mathrm{g}$ can be expressed in kilogram as $0.002\mathrm{kg}$.
