A conversion is a special type of ratio used to convert from one unit of measurement to another. These ratios are known as conversion factors.

### Example

Suppose we wanted to know how many inches are in $3$ feet. Since we know there are $12$ inches in a foot, our conversion factor is $\frac{12\text{ inches}}{1\text{ feet}}$. Thus, there are $$3\;\cancel{\text{feet}}\cdot\frac{12\text{ inches}}{1\;\cancel{\text{feet}}}=\boxed{36\;\text{inches}}$$ in $3$ feet.
