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.
