The measurements are used to calculate, compare and present a condition. The example below shows that on an average cheetah can run 60 mph. However, a cheetah can't run forever, therefore, we use measurements to describe a condition. Now you would imagine that when a cheetah has to catch it's prey, it can pick up speed up to 60 mph. Here a label is describing a condition where we use a division.

In a similar way, a label can also show the result of multiplication. The example below, explains that a 50 watt bulb uses the amount of energy in 60 seconds.

(50 watts)(60 seconds) = 50 watt.sec = joule
