# How to convert gallons to quarts, quarts to pints, pints to cups, and cups to ounces | Khan Academy

We have noted here two volumes or two liquid volumes. They are in gallons – 1 gallon and 2 gallons. In this clip I want to try to convert that volume of liquid in other units of the American Measurement System. So I advise you to pause the video and try one gallon first Try to make quarts, pints, glasses and ounces. There are 4 quarts in one gallon. So we can just multiply by 4. There are 2 pints in one block, so we can multiply that by 2. So 4 quarts, each with 2 pints, 4 by 2 makes 8 pints.

Each pint is equal to 2 glasses, so we have 8 pints, each containing 2 glasses. We will have 16 glasses. Finally turn from cups in fluid ounces, there are 8 fluid ounces in each glass If we have 16 glasses, it will be 16 by 8. 8 by 8 is 64 and we will have 2 times on this thing. This will be 128 fluid ounces. Now let’s do the same thing with 2 gallons. Let’s try to make quarts, pints, glasses and ounces. Again, I suggest you stop the video and try it yourself first. The idea is the same. There are 4 quarts in one gallon. So in 2 gallons there will be 2 quarts or 8 quarts. The quart is 2 pints. So if we want to go from quart to pint, we will have to multiply by 2 That’s 16 pints. And then, there are 2 glasses in each pint. We multiply 16, so it will become 32 cups. Finally, there are 8 ounces in each glass. 32 to 8 e … Let’s see it will be 256. Please note the following here: when we went from 1 gallon to 2 gallons, we increased the amount of gallons twice, or multiplied by 2. You can see that on the board, we’re through from 4 quarters to 8 quarters, The 8 pints became 16 pints, The 16 glasses became 32 glasses.

And the 128 ounces became 256. When we increase the volume of gallons 2 times, it is clear that we will increase the volume of each of units 2 times.
