Using the Metric System

S.I. units are so easy to work with because they are based on multiples of 10!


How easy is this???

  • There has to be a better way…

Converting Standard Measurements


In The Metric System…

  • There is one basic unit for…

    • Length (meter)

    • Volume (liter)

    • Mass (gram)

  • Each smaller unit is easy to convert to the larger unit and vice versa!

    • This chart can be used for each of the basic units

    • The values do not change for liters…

    • Or Grams!


Using the Metric System is easy!!!

  • To simplify things, very large and very small objects are expressed as multiples of ten of the base unit

    • For example… A “5,000” meter long race can also be written as a “five thousand” meter, or as “5K” (5 kilometer) long race!

    • A grain of salt is “0.001” meters long, or “one one-thousandth of a meter, or “millimeter” in length

  • Metric prefixes can be used with any base unit

    • For example…

      • A kilometer is 1,000 meters

      • A kilogram is 1,000 grams

      • A kiloliter is 1,000 liters


Using the Metric System is easy!!!

  • Base the subunit you use on whichever is closest to the size of the object you are measuring

    • It wouldn't make sense to measure your weight in grams for the same reason that you wouldn't measure it in ounces - the unit is too small

    • You would express your weight in a unit that makes sense, in this case: kilograms, because 1 kilogram is equal to 1000 grams

    • (1 kilogram = 2.2 lbs)

1 kilogram

1000 grams

They are the same!


How do I do it?

  • The metric system is based on multiplying or dividing your units by 10

    • This moves your decimal point to the left or right

    • It does NOT change the numbers you use! 

  • The six important prefixes used in the Metric System are…
