How to Convert Quarts to Fluid Ounces

To convert a measurement in quarts to a measurement in fluid ounces, multiply the volume by the following conversion ratio: 32 fluid ounces/quart.

Since one quart is equal to 32 fluid ounces, you can use this simple formula to convert:

fluid ounces = quarts × 32

The volume in fluid ounces is equal to the volume in quarts multiplied by 32.

For example, here's how to convert 5 quarts to fluid ounces using the formula above.

fluid ounces = (5 qt × 32) = 160 fl oz

How Many Fluid Ounces Are in a Quart?

There are 32 fluid ounces in a quart, which is why we use this value in the formula above.

1 qt = 32 fl oz

Quarts and fluid ounces are both units used to measure volume. Keep reading to learn more about each unit of measure.

What Is a Quart?

The US liquid quart is a unit of fluid volume equal to one fourth of a gallon, two pints, or four cups.

The liquid quart should not be confused with the dry quart (US) or the imperial quart, which are different units. However, when someone refers to a volume in quarts, they typically mean the US liquid quart.

The quart is a US customary unit of volume. Quarts can be abbreviated as qt; for example, 1 quart can be written as 1 qt.

What Is a Fluid Ounce?

The US fluid ounce is a unit of volume equal to 1/16 of a pint or 1/8 of a cup. The fluid ounce is sometimes referred to as just an "ounce" but should not be confused with the unit of weight. One fluid ounce is equal to approximately 29.5735 milliliters, but in nutrition labeling, one fluid ounce is rounded to exactly 30 milliliters.[1]

The fluid ounce is a US customary unit of volume. Fluid ounces can be abbreviated as fl oz, and are also sometimes abbreviated as oz fl. For example, 1 fluid ounce can be written as 1 fl oz or 1 oz fl.
