## How to Convert Ounces to Quarts

Since ounces are a unit of mass and quarts are a unit of volume, which are different physical quantities, we need to know one more physical quantity of the ingredient or substance to convert between them. In this case, we need to account for the density of the substance whenever we do a conversion.

Therefore, to convert between ounces and quarts of an ingredient or substance, we must either multiply or divide by its density, depending on which direction we are performing the conversion.

### Ounces to Quarts Formula

To convert a measurement in ounces to quarts, divide the weight by the density of the ingredient or material. Note that in order for this to work, the density must be in ounces per quart (oz/qt).

If the density is given in grams per milliliter (g/mL), then first multiply the density by 33.3816 to convert to oz/qt.

For a density given in g/mL, you can use this simple formula to convert:

quarts = ounces / 33.3816 × density

Thus, the volume in quarts is equal to the weight in ounces divided by 33.3816 times the density (in g/mL) of the ingredient, substance, or material.

For example, here's how to convert 5 ounces to quarts for an ingredient with a density of 0.7 g/mL.
quarts = 5 oz / 33.3816 × 0.7 g/mL = 0.214 qt

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

## When to Convert Ounces to Quarts

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 and clumping.

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.

Another useful application of weight and volume conversions is chemistry. When performing chemical reactions by combining separate chemicals to produce a new chemical, one must know the exact amount of each chemical to add in order to maximize the yield of the reaction.

It is common to mix powdered chemicals with liquid, or aqueous, chemicals, and this is where it becomes very useful to convert between weights and volumes.[2]

## What Is an Ounce?

One ounce is a unit of mass/weight equal to 1/16 of a pound or 28.349523 grams. The common ounce should not be confused with the troy ounce, which is equal to 1/12 of a troy pound.[3]

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

An ounce is frequently referred to as a unit of weight. While technically, an ounce is a measure of mass, and weight is actually a measure of force, the two are equivalent as long as we are performing our calculations on Earth.

For example, an object with a mass of 1 ounce weighs 1 ounce on Earth, but only weighs one-sixth of that on the moon, yet still has the same mass.

## 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.
