How to Convert Tablespoons to Pounds

To convert a tablespoon measurement to a pound measurement, divide the volume multiplied by the density of the ingredient or material by 30.675565.

You can use this simple formula to convert:

pounds = tablespoons × ingredient density / 30.675565

Thus, the volume in pounds is equal to the tablespoons times the density of the ingredient or material divided by 30.675565.

For example, here's how to convert 5 tablespoons to pounds for an ingredient with a density of 0.7 g/mL.
5 tbsp = 5 × 0.7 / 30.675565 = 0.114097326498 lb

Tablespoons 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.

For cooking and baking ingredients, you can get more specific results using our butter, flour, sugar conversion calculators.

Tablespoons

The tablespoon is a unit of volume equal to three teaspoons or ½ fluid ounce.[2] One tablespoon is equal to just under 14.8 milliliters, but in nutrition labeling, one tablespoon is equal to 15 milliliters.[3]

The tablespoon is a US customary unit of volume. Tablespoons can be abbreviated as tbsp, and are also sometimes abbreviated as T, Tbls, or Tb. For example, 1 tablespoon can be written as 1 tbsp, 1 T, 1 Tbls, or 1 Tb.

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.[4]

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.[5]

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 #.
