Since quarts are a unit of volume and grams are a unit of mass, 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 quarts and grams of an ingredient or substance, we must either multiply or divide by its density, depending on which direction we are performing the conversion.

Quarts to Grams Formula

To convert a measurement in quarts to grams, multiply the volume by the density of the ingredient or material. Note that in order for this to work, the density must be in grams per quart (g/qt).

If the density is given in grams per milliliter (g/mL), then first multiply the density by 946.3529 to convert to g/qt.

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

grams = quarts × 946.3529 × density

Thus, the weight in grams is equal to the volume in quarts multiplied by 946.3529 times the density (in g/mL) of the ingredient, substance, or material.

When to Convert Quarts to Grams

Quarts and grams 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 volume to weight 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]

How Many Grams Are in a Quart?

The actual weight of a quart will vary depending on the density of the material. The table below shows how many grams of various wet and dry ingredients are in a quart.
