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

You can use this simple formula to convert:

ounces = quarts × 33.381618 × ingredient density

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

For example, here's how to convert 5 quarts to ounces for an ingredient with a density of 0.7 g/mL.
5 qt = 5 × 33.381618 × 0.7 = 116.835662 oz

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

Quarts and ounces 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 volume to weight conversion.

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.
