• Convert customary and metric units of length, weight or
mass, capacity, and time.
• unit ratio
Standard 7MG1.1 Compare weights, capacities, geometric
measures, times, and temperatures within and between
measurement systems (e.g. miles per hour and feet per
second, cubic inches to cubic centimeters).
We will handout a set of charts you will need to use.
Convert Larger Units to Smaller Units
Convert 21/2 pounds to ounces.
1 pound = 16 ounces
Pounds are larger than ounces.
When converting from a larger unit to a smaller one MULTIPLY.
Change any fraction to a decimal 1st.
21/2 lbs = 2.5lbs
2.5 lbs  16 oz = 40 oz
Convert Smaller Units to Larger Units
SHIPPING Cristos is shipping a package of model train parts. The sum of the
weights of the parts is 900 grams. What is the weight of the parts in kilograms?
1000gram = 1kilogram
Grams are smaller than kilograms.
When converting from a smaller unit to a larger one DIVIDE.
Change any fraction to a decimal 1st.
There are no fractions to change in this problem.
900g &divide; 1000g = 0.9kg
Convert Between Systems
Convert 10 miles to kilometers. Round to the nearest hundredth.
1 kilometer= 0.621mile
Miles are larger than kilometers.
When converting from a larger unit to a smaller one MULTIPLY.
