Converting quarts to gallons is a simple division calculation. This lesson will walk you through the steps and offer problems for you to learn the steps involved.

Convert Quarts to Gallons

To make this conversion, we've got to use the knowledge that there are 4 quarts in every gallon.

  • 4 Quarts = 1 Gallon

Thus, to convert quarts to gallons, you just need to divide the number of quarts by four (4/4=1).

Let's find out how many gallons there are in 28 quarts of a substance.

Step 1

Divide the number of quarts by 4:

28/4 = 7

Step 2

Include the unit of measurement in the answer:

7 gallons

So it turns out there are 7 gallons for every 28 quarts of a substance.

Formatting Our Solution

You can either write out the word 'gallon' or you can abbreviate the word to 'gal.'; either way is appropriate for a properly formatted answer.

So, for the problem above, the two forms of our answer are:

7 gallons or 7 gal.

Some Tips and Another Example


If your quotient is not whole, it is generally accepted to round the answer to two place values after the decimal.

For example, how many gallons are in 257 quarts?

257/4 (the fraction bar is another form of the divide symbol) = 64.25

Solution is: 64.25 gallons.
