Question

If the height of a person is $1.65\mathrm{m}$.

Convert the meters ($\mathrm{m}$) into centimeters ($\mathrm{cm}$) and millimeters ($\mathrm{mm}$).

Answer 1

Step 1: Convert meter to centimeter

Given, height of the person is $1.65\mathrm{m}$.

We know that,
$1\mathrm{m}=100\mathrm{cm}$
Multiplying both sides by $1.65$,
$\begin{array}{cc}\Rightarrow & 1\times 1.65\mathrm{m}=100\times 1.65\mathrm{cm}\\ \Rightarrow & 1.65\mathrm{m}=165\mathrm{cm}\end{array}$

Therefore, $1.65\mathrm{m}=165\mathrm{cm}$

Step 2: Convert centimeter into millimeter

We know that,
$1\mathrm{cm}=10\mathrm{mm}$
Multiplying both sides by $1.65$,
$\begin{array}{cc}\Rightarrow & 1\times 165\mathrm{cm}=10\times 165\\ \Rightarrow & 165\mathrm{cm}=1650\mathrm{mm}\end{array}$
Therefore, $165\mathrm{cm}=1650\mathrm{mm}$

But we know that, $165\mathrm{cm}=1.65\mathrm{m}$

Therefore, $1.65\mathrm{m}=1650\mathrm{mm}$

Hence, $1.65\mathrm{m}$ is equal to $165\mathrm{cm}$ and $1650\mathrm{mm}$.
