The metric system is straightforward to use for conversions between larger and smaller units. To convert from a larger to a smaller metric unit, you multiply, while converting from a smaller to a larger unit involves dividing. The Latin prefixes indicate quantities, e.g., 1 kilogram equals 1000 grams (kilo means 1000). As you move one step up in the metric chart, divide by 10 (move the decimal left), and as you move down, multiply by 10 (move the decimal right). Let's practice with some conversions: 3 meters to centimeters, 40 liters to dekaliters, and more!

To convert from a larger to smaller metric unit you always multiply • To convert from a smaller to larger unit you always divide • The Latin prefixes used in the metric system literally mean the number they represent. Example: 1 kilo gram = 1000 grams A kilo is 1000 of something • Just like a dozen is 12 of something
For every step upward on the chart you are dividing by 10 or moving the decimal one place to the left. • When you move down the stairs you are multiplying by 10 for each step. SO you are adding a zero to your original number and moving the decimal one place to the right with each step.
Try Some… 1.) 3 meters = ______ centimeters 2.) 40 liters = ______ dekaliters 3.) 600 milligrams = _______ grams 4.) 5 kilometers = __________ hectometers 5.) 70 centimeters = _________ meters 6.) 900 deciliters= _______ dekaliters
