How to Convert Quarts to Pounds

To convert a quart measurement to a pound measurement, multiply the volume by 2.086351 times the density of the ingredient or material.

You can use this simple formula to convert:

pounds = quarts × 2.086351 × ingredient density

Thus, the volume in pounds is equal to the quarts multiplied by 2.086351 times the density of the ingredient or material.

For example, here's how to convert 5 quarts to pounds for an ingredient with a density of 0.7 g/mL.
5 qt = 5 × 2.086351 × 0.7 = 7.302229 lb

Quarts and pounds 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.


Pounds are a widely used unit of mass/weight in the United States. The National Bureau of Standards approved the international definition of the pound for use in the United States in 1959 after an agreement between six nations referred to as the International Yard and Pound Agreement.[2]

One pound is equal to 16 ounces, or 0.45359237 kilograms. In the avoirdupois or apothecaries' systems, one pound is equal to 7,000 grains.[3]

The pound is a US customary and imperial unit of weight. A pound is sometimes also referred to as a common ounce. Pounds can be abbreviated as lb, and are also sometimes abbreviated as lbs, lbm, or #. For example, 1 pound can be written as 1 lb, 1 lbs, 1 lbm, or 1 #.
