To perform a conversion between 2 units, a quantity given in a particular unit is converted into another unit. This type of conversion is as follows:

$\left(\text{quantity given}\right)\times \left(\text{conversion factor}\right)=\left(\text{quantity sought}\right)$

A conversion factor is a fraction in which the numerator is the unit into which the quantity is to be converted and the denominator is the unit from which it is converted.
