The Metric System
The Metric System is a system of measurement that uses base
units and prefixes. The base you use depends on what you're
measuring. This goes for the prefixes as well. Converting is easy
using this system because all of the units are based on multiples
of 10. This system is used all over the world except for here in
the United States.

Metric Weight Conversions
1,000 milligrams (mg) = 1 gram (g)
1,000 grams (g) = 1 kilogram (kg)
If a paperclip weighs about one gram, can you
imagine how small something has to be to weigh
only a milligram?! This also means that something
weighing one kilogram would weigh about the same
as 1,000 paperclips.

1,000 liters (L) = 1 kiloliter (kL)
When you go to the grocery store and buy a
bottle of soda, those bottles are about
equal to 2 liters.
Metric Weight

About 20 to 25 drops from a dropper would
equal about 1 milliliter.

Since there are 1,000 liters in 1 kiloliter, then it
would take 500 2 liter sodas from the grocery
store to equal 1 kiloliter.
