Measurement-A Common Language Metric system.

Metric System • A system of measurement used by the majority of countries on Earth based on the number 10 • Some times called the S. I. system

Basic Measurements • Meter – measures length • Liter – measures volume • Gram – measures mass

Converting • Some times we need to go from one size to another size. • So we give each different size a pre-fix.

Metric Units

How to Convert • Step 1: Determine if you are going to go up or down the ladder. • Step 2: Determine how many steps there are from the units you started with to the units you need to get to. • Step 3: Move the decimal point the same amount of places and in the same direction as in steps 1 & 2.
