How to Convert Pounds to Liters

To convert a pound measurement to a liter measurement, divide the weight by 2.204623 times the density of the ingredient or material.

You can use this simple formula to convert:

liters = pounds2.204623 × ingredient density

Thus, the weight in liters is equal to the pounds divided by 2.204623 times the density of the ingredient or material.

For example, here's how to convert 5 pounds to liters for an ingredient with a density of 0.7 g/mL.

5 lb = 52.204623 × 0.7 = 3.239946 l

Pounds and liters 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 weight to volume conversion.

Pounds

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, lb_m, or #. For example, 1 pound can be written as 1 lb, 1 lbs, 1 lb_m, or 1 #.

Liters

A liter is a unit of volume equal to 1,000 cubic centimeters.^[4] The liter is a special name defined for the cubic decimeter and is exactly equal to the volume of one cubic decimeter.

The liter is an SI accepted unit for volume for use with the metric system. A liter is sometimes also referred to as a litre. Liters can be abbreviated as l, and are also sometimes abbreviated as L or ℓ. For example, 1 liter can be written as 1 l, 1 L, or 1 ℓ.
