5. The metric system uses prefixes before the common base SI unit to describe something that is larger or smaller. For example, the base SI unit for length is the meter. The prefix would be placed before the word meter to show how much smaller or bigger than a meter that particular length is.

7. The Rules to Measuring Successfully in the Metric System
No fractions for measuring!!!
Example: ½ = 0.5
Always have a number before and after a decimal.
