1. METRIC SYSTEM

2. 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

3. How to do metric System Conversions
Step 1- Determine your starting point
Step 2-Determine your ending point
Step 3- Mark your direction
Step 4- count the jumps
ALWAYS PLACE THE DECIMAL AT THE END OF THE NUMBER

4. How many jumps does it take?
Ladder Method 1 2 3
KILO 1000 Units
HECTO 100 Units
DEKA 10 Units
DECI 0.1 Unit
Meters Liters Grams
CENTI 0.01 Unit
MILLI Unit
How do you use the “ladder” method?
1st – Determine your starting point.
2nd – Count the “jumps” to your ending point.
3rd – Move the decimal the same number of jumps in the same direction.
