Hint: Meter and kilometer are the units of length. If we want to convert a length from one unit to another unit, we have to multiply or divide it by some constant. To convert the length cm to meter, we divide the length in cm by 100. To convert a length given in cm to kilometer, we have to divide the length in cm by 100000.
To convert a length $l$ given in cm to meter, we have to divide the length l in cm by 100 to convert in meter. Mathematically, we have,
$l$ (in cm) = $\dfrac{l}{100}$ (in meter) $..............\left( 1 \right)$
$l$ (in cm) = $\dfrac{l}{100000}$ (in kilometer) $..............\left( 2 \right)$
Using formula $\left( 1 \right)$, the length 5 cm in meter is equal to,
\begin{align} & \dfrac{5}{100}m \\ & \Rightarrow 0.05m \\ \end{align}
Using formula $\left( 1 \right)$, the length 5 cm in kilometer is equal to,
\begin{align} & \dfrac{5}{100000}km \\ & \Rightarrow 0.00005km \\ \end{align}
