Customary Units of Measurement for Capacity
By Mrs. Powell

Units of Measure Gallons Quarts Pints Cups ounces

There are 4 quarts in every gallon.
How many quarts would there be in 3 gallons? How many gallons are there in 48 quarts?

How did you do that? Why did you use that operation?
How many quarts would there be in 3 gallons? Yes, you’re correct. There are 12 quarts in 3 gallons? What operation did you use to answer that question? Why did you use that operation?

How did you do that? How many gallons are there in 48 quarts?
Yes, you’re correct again. There are 12 gallons in 48 quarts. What operation did you use to solve that problem? Why did you use that operation?

There are 2 pints in every quart.
How many pints are in 4 quarts? How many quarts are in 10 pints?

How did you do that? Yes, you’re correct again!
How many pints are in 4 quarts? Yes, you’re correct again! There are 8 pints in 4 quarts. ( How many pints in a gallon?) What operation did you use to do that? Why did you use that operation?

How did you do that? WOW! There you go again!
How many quarts are in 10 pints? WOW! There you go again! There are 5 quarts in 10 pints. What operation did you use to figure that out? Why did you use that operation?

There are 2 cups in every pint.
How many cups would there be in 12 pints? How many pints would there be in 6 cups?

How did you do that? You’re batting a 1000!
How many cups are in 12 pints? You’re batting a 1000! There are 24 cups in 12 pints. What operation did you use? Why did you use that operation?

How did you do that? You’re going strong! There are 3 pints in 6 cups.
How many pints are in 6 cups? You’re going strong! There are 3 pints in 6 cups. What operation did you use? Why did you use that operation?

There are 8 ounces in every cup.
How many ounces are in 5 cups? How many cups are in 32 ounces?

How did you do that? You are awesome! There are 40 ounces in 5 cups.
How many ounces (oz) are in 5 cups? You are awesome! There are 40 ounces in 5 cups. What operation did you use? Why did you use that operation?

How did you do that? You’re blowin’ me away!
How many cups are in 32 oz.? You’re blowin’ me away! There are 4 cups in 32 ounces. What operation did you use? Why did you use that operation?

Have you figured out . . . THE TRICK?

To change from a larger unit to a smaller unit you should . . .
Because you need more of the smaller unit

To change from a smaller unit to a larger unit
you should . . . Because you don’t need as many of the big units

Larger Unit Smaller Unit

Practice Makes Perfect
Delia is throwing a party. She had 3 gallons of punch. If each guests gets 2 cups, how many guests will be at her party?

48 3 gallons ____ cups. THINKIN OUT LOUD! 1 gallon = 4 quarts so
3 gallons x 4 quarts in a gallon = 12 quarts. 1 quart = 2 pints and 2 pints x 2 cups in a pint= 4 cups so 1quart = 4 cups. You still with me? Remember 3 gallons = 12 quarts so 12 quarts x 4 cups in each quart = 48 cups There are 48 cups in 3 gallons!
