# How many meters is 120 cm?

Sep 3, 2016

$120 \cdot c m = 1.20 \cdot m$

#### Explanation:

$1 \cdot c m$ $=$ $1 \times {10}^{-} 2 \cdot m$

Thus $120 \cdot c m = 120 \times 1 \times {10}^{-} 2 \cdot m$ $=$ $1.20 \cdot m$.

$\text{Centi}$, $\text{micro}$, $\text{milli}$, and $\text{kilo}$ are simply commonly used mulitpliers to save on the number of $0000 \text{'s}$ we have to write.

$\text{Micro } \left(\mu\right)$ means $\times {10}^{-} 6$.

$\text{Milli (m)}$ means $\times {10}^{-} 3$.

$\text{Kilo (k)}$ means $\times {10}^{3}$.

$\text{Mega (m)}$ means $\times {10}^{6}$.

$\text{Deci}$ means $\times {10}^{-} 1$.
