Convert Customary Units of Capacity

Example 1) How many cups in 7 quarts?

The measurement facts we need is 1 pint = 2 cups and that 1 quart = 2 pints.

So to convert quarts into cups, first we need to convert quarts into pints by multiplying the number by 2.

7 quarts = 7 x 2 = 14 pints.

Secondly we need to convert pints into cups by multiplying the number by 2.

14 pints = 14 x 2 = 28 cups

So 7 quarts is equal to 28 cups.

Example 2) How many fluid ounces in 6 &fra12; pints?

The measurement fact we need is 1 pint = 16 fluid ounces.

So to convert pints into fluid ounces we need to multiply the number by 16.

6 ½ pints = 6 ½ x 16 = 104 fluid ounces.

So 6 ½ pints = 104 fluid ounces.

Example 3) Captain has 500 fluid ounces of water which he puts into gallon containers. How many containers will he need to hold all the water?

The measurement fact we need is 1 gallon = 128 fluid ounces.

So to convert fluid ounces into gallons, we need to divide the number of fluid ounces by 128.

500 fluid ounces = 500 ÷ 128 = 3.90625 gallons

So he will need 4 gallon containers to hold all the water.

Example 4) Tyger makes 215 pints of squash which he pours into a 20 gallon container. How much squash is left over?

The measurement fact we need is 1 gallon = 8 pints.

The 20 gallon container will hold 20 x 8 = 160 pints.

Tyger makes 215 pints. 215 - 160 = 55.

There will be 55 pints of squash left over.

Example 5) Sally makes 3 gallons of a non-alcoholic fruit punch for a party. There are 15 guests at the party. How many whole cups will each guest be able to have?

The measurement fact we need is 1 gallon = 8 pints and 1 pints = 2 cups.

So each gallon will make 8 x 2 = 16 cups.

Sally has made 3 gallons which is 16 x 3 = 48 cups.

There are 15 guests, so each guest will be able to have 48 ÷ 15 = 3.2 cups.

Each guest will be able to have 3 whole cups.
