“What does the Metric System measure?” Length - meters, m Mass – grams, g Volume - liters, L Time - seconds, s Temperature - Celsius, ºC

Metric Conversion (Staircase Method) To convert to a smaller unit, move decimal point to the right Kilo (k) 1000 units Hecto (h) 100 units Deka (da) 10 units Basic Unit (m, g, L) Deci (d) 0.1 units Centi (c) 0.01 units Milli (m) 0.001 units To convert to a larger unit, move decimal point to the left

For example… 7 3 7000 mg = ____ g Kilo (k) 1000 100 10 Basic Unit units Hecto (h) 100 units Deka (dk) 10 units Basic Unit (m, g, L) Deci (d) 0.1 units Centi (c) 0.01 units Milli (m) 0.001 units Step 1: Determine if you are going to go left or right on the staircase. Step 2: Determine how many steps there are from milligrams to grams. 3 Step 3: Move the decimal that many places.

Let’s practice… 150 .2 470,000 20 cm = _________ m .15 L = _________ mL .2 20 cm = _________ m 470,000 .47 km = _________ mm
