From infrastructure construction to landscaping design, familiarity with conversion of units is very important. Calculating the amount of asphalt needed on a paving job and determining the quantity of river rocks necessary to cover a given area in a specific landscape design, are everyday examples of the necessity of being able to move from given data to needed quantities. Moving from different units of measurement that are actually the same quantity requires the use of conversion factors.
