# How do you convert 345 cm to inches?

$\frac{345 \cdot c m}{2.54 \cdot c m \cdot {\text{inch}}^{-} 1}$ $=$ ?? $\text{inches}$
The answer given is consistent dimensionally, i.e. $\frac{345 \cdot \cancel{c m}}{2.54 \cdot \cancel{c m} \cdot {\text{inch}}^{-} 1}$ for an answer in $\frac{1}{{\text{inch}}^{-} 1}$ $=$ $\text{inches}$, i.e. $\frac{1}{\frac{1}{x}} = x$.
