# How many metres are in one centimetre?

Nov 24, 2016

$1 \cdot m$ $=$ ${10}^{2} \cdot c m$ $=$ ${10}^{3} \cdot m m$
And thus in $\text{1 metre}$, there are $\text{100 cm}$, and $\text{1000 mm}$.
The prefix $\text{centi} = {10}^{-} 2$, and $\text{millli} = {10}^{-} 3$; $\text{deci} = {10}^{-} 1$.
And thus $1 \cdot c m$ $=$ $10 \cdot m m$ $=$ $0.01 \cdot m$.
