How to Convert Ounces to Quarts

To convert an ounce measurement to a quart measurement, divide the weight by 33.381618 times the density of the ingredient or material.

You can use this simple formula to convert:

quarts = ounces / 33.381618 × ingredient density

Thus, the weight in quarts is equal to the ounces divided by 33.381618 times the density of the ingredient or material.

For example, here's how to convert 5 ounces to quarts for an ingredient with a density of 0.7 g/mL.
5 oz = 5 / 33.381618 × 0.7 = 0.213975763066 qt

This calculator converts ounces in weight, if you're trying to convert a volume measurement in fluid ounces try our fluid ounces to quarts calculator.

Ounces and quarts are both commonly used to measure cooking ingredients.

For cooking applications, most chefs suggest measuring dry ingredients by weight rather than volume to improve accuracy in the measurements.[1] The density of dry ingredients can vary for a variety of reasons, such as compaction.

The best way to ensure an accurate conversion is to use a scale. When a scale is not available, a calculator like the one above is a good way to estimate the weight to volume conversion.

Ounces

One ounce is a unit of mass/weight equal to 1/16 of a pound. The common ounce should not be confused with the troy ounce, which is equal to 1/12 of a troy pound.[2]

The ounce is a US customary and imperial unit of weight. Ounces can be abbreviated as oz; for example, 1 ounce can be written as 1 oz.

Quarts

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.

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.
