WHY DO WE USE THE METRIC SYSTEM?
Almost all other countries are using the metric system
Other countries’ companies are refusing to buy products from the U.S. if not labeled in metric units
Scientists need a universal way to communicate data

WHAT DOES THE METRIC SYSTEM MEASURE?
The gram measures mass or how much something weighs
The liter measures volume which is used when measuring liquids
The meter measures the length of an object or the distance from place to place

Metric System• The metric system is based on a base
unit that corresponds to a certain kind of measurement
• Length = meter• Volume = liter• Weight (Mass) = gram
• Prefixes plus base units make up the metric system – Example:
• Centi + meter = Centimeter• Kilo + liter = Kiloliter

Metric System• The three prefixes that are used
the most are:– kilo– centi– milli
kilo hecto deca

TRY THIS USING THE STAIRCASE METHOD
1000 mg = ______ g
Step 1: Determine if you are going to go up or down the ladder.Step 2: Determine how many steps there are from milligrams to grams.Step 3: Move the decimal point the amount of places that was determined in steps 1 & 2.
