How to Convert Fluid Ounces to Quarts

To convert a measurement in fluid ounces to a measurement in quarts, divide 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:

quarts = fluid ounces ÷ 32

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

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

quarts = (5 fl oz ÷ 32) = 0.15625 qt

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

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.

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.
