# How do you convert 345 cm to miles?

Sep 22, 2016

$\text{1 mile}$ $\equiv$ $1.609 \cdot k m$ $=$ $1.609 \times {10}^{5} \cdot c m$

#### Explanation:

$\text{1 mile}$ $\equiv$ $1.609 \cdot k m$ $=$ $1.609 \times {10}^{3} \cdot m$

$=$ $1.609 \times {10}^{3} \cdot \cancel{m} \times {10}^{2} \cdot c m \cdot \cancel{{m}^{-} 1}$ (because $1 \cdot m \equiv 100 \cdot c m$).

$=$ $1.609 \times {10}^{5} \cdot c m$

And thus, $345 \cdot c m$ $=$ $\frac{345 \cdot \cancel{c m}}{1.609 \times {10}^{5} \cdot \cancel{c m} \cdot {\text{mile}}^{-} 1}$ $=$ ??"mile"

Is there any move in the States to adopt the metric system?
