Unit Conversion
Noreen wants to know whether she used more or less than 25 gallons of water. How can she compare 320 cups to 25 gallons?
One way is to convert 320 cups into an equivalent number of gallons.
Doing a unit conversion does not change the amount of water that she used. It just allows her to measure the water using another unit of measurement: gallons instead of cups.
Click on the left to see Noreen convert 320 cups into gallons. After watching, keep reading below and answer the question.
Sixteen (16) cups is equivalent to one (1) gallon. Noreen divides 320 ÷ 16 and calculates that this is equal to 20 gallons. A gallon is larger than a cup, so it makes sense that 20 gallons is equivalent to 320 cups.
Since 20 gallons is less than 25, Noreen's water usage is below average.
Now think about this: Dustin did the same experiment and found that he used 240 cups of water in the shower. In one to two sentences, explain how he can figure out how many gallons this is equivalent to. Include the word "convert" in your answer.
