If you are in any other country in the world and say what the temperature is in Fahrenheit, they will not be able to understand what you mean. They use Celsius, and you have to convert it to Celsius.
If you are asked to give a medication in a dose of 18 mg/kg, and the person weighs 154 pounds, how many kg are in 154 pounds?
If you are in Europe, they measure fuel economy by number of liters of fuel it takes to go 100 km. In order to do this, you need to convert gallons to liters and miles to kilometers. These are a few of the examples, and this is just metric-English. There are many other equations in multiple variables that one may have to solve to determine, for example, what percentage of a change is due to normal variability and what is due to a change in the system itself.
