# How do you convert 9000 cm to meters?

$\text{Divide the number by 100?}$
The $\text{centi}$ prefix in $\text{centimetre}$ means $\times {10}^{-} 2$.
Thus $9000 \cdot c m$ $=$ $9000 \times {10}^{-} 2 \cdot m$ $=$ $9 \times {10}^{3} \times {10}^{-} 2 \cdot m$ $=$ $9.0 \times {10}^{1} \cdot m$ $=$ $90 \cdot m$
