Question

Express as kilometers using decimal:

$8\mathrm{m}$.

Answer 1

Convert the unit from meter to kilometer:

Given length: $8\mathrm{m}$.

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

Thus, $8\mathrm{m}=\left(8\times 0.001\right)\mathrm{km}=0.008\mathrm{km}$.

Hence the given length can be expressed in kilometer as $0.008\mathrm{km}$.
