We can measure how big things are, how warm they are, how heavy they are, and lots of other features as well. Units of Measurement provide standards for our comparisons, so that the numbers from our measurements refer to the same thing. For example, the metre is a standard unit to measure length.he property of the thing being measured is given as a number of units of measure. The number only has sense when the unit of measurement is also given. For example, The Eiffel Tower in Paris, France is 300 meters tall. That is, the distance from the top to the bottom of the Eiffel Tower is 300 meters.
