## 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…
