Question

The height of a person is $1.65m$. Express it into $cm$ and $mm$.

Answer 1

Conversion of unit:

To convert a value from meters $\left(m\right)$ into centimeters $\left(cm\right)$, it must be multiplied by $100$. Mathematically, it can be expressed as $m\times 100=cm$.

To convert a value from meters $\left(m\right)$ into millimeters $\left(mm\right)$, it must be multiplied by $1000$. Mathematically, it can be expressed as $m\times 1000=mm$

Convert the height into centimeters using the formula.

$\begin{array}{rcl}h& =& 1.65m\\ & =& 1.65\times 100cm\\ & =& 165cm\end{array}$

Convert the height into millimeters using the formula.

$\begin{array}{rcl}h& =& 1.65m\\ & =& 1.65\times 1000mm\\ & =& 1650mm\end{array}$

Hence, the height of the person in $cm$ is $165cms$ and in $mm$ is $1650mms$.
