Conversion Stand up and Measure the height (length) of your table buddy in meters – record in your notes Convert to kilometers What was the multiplier? Convert to centimeters?
Weight the amount or quantity of heaviness or mass Base Unit Grams What is your weight in Kg? Convert pounds to Kg (lbs / 2.2) Convert to grams Convert to milligrams
Volume Units of volume include: The amount of 3-dimensional space an object occupies. Capacity. Base Unit Liter or Metric: cubic centimeters (cm3), cubic meters (m3),
CONVERT A graduated cylinder has 1 Liter of liquid. How much liquid in milliliters? How much liquid in kiloliters? How much liquid in pints? pints (2.11 pints in 1 liter or 0.4732 liters in each pint) Complete these problems and show your work! Now show all these measurements of equal
THINK A Penny has a mass of approximately 2.5 grams. How many pennies does it take to make 1 kg? How many pieces would you need to break to two pennies into to have a mass of a milligram?
Volume of a cube The height of a a cube is 1 meters, the length is 1 meter, and the width is 1 meter. What is the capacity or volume of the cube? Make sure the units are correct. What is this capacity or volume in mL (1 cubic meter (m3) = 1000 mL
Use Ladder Method
Know This 1000 mL = 1 liter (they are the same) 100 cL = 1 liter (they are the same) 10 dl = 1 liter (they are the same) Fill in the answers below 1 gram = mg (they are the same) 1 meter = cm (they are the same) 1 kilometer is meters (same)
