How to Convert Pounds to Quarts

Since pounds 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 pounds 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.

Pounds to Quarts Formula

To convert a measurement in pounds 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 pounds per quart (lb/qt).

If the density is given in grams per milliliter (g/mL), then first multiply the density by 2.0864 to convert to lb/qt.

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

quarts = pounds / 2.0864 × density

Thus, the volume in quarts is equal to the weight in pounds divided by 2.0864 times the density (in g/mL) of the ingredient, substance, or material.

When to Convert Pounds to Quarts

Pounds 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]

A third application of weight and volume conversions is when shipping freight when calculating the volumetric weight for cargo and packages. Trucks, ships, and airplanes are limited in the amount of weight or volume they can transport, so if one of those quantities is known, but the limitation is on the other, then it becomes necessary to convert between the two so as not to overload the shipping vehicle.
