How to Convert Teaspoons to Pounds

Since teaspoons are a unit of volume and pounds are a unit of mass, 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 teaspoons and pounds of an ingredient or substance, we must either multiply or divide by its density, depending on which direction we are performing the conversion.

Teaspoons to Pounds Formula

To convert a measurement in teaspoons to pounds, multiply the volume by the density of the ingredient, substance, or material. Note that in order for this to work, the density must be in pounds per teaspoon (lb/tsp).

If the density is given in grams per milliliter (g/mL), then first divide the density by 92.0267 to convert to lb/tsp.

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

pounds = teaspoons × density / 92.0267

Thus, the weight in pounds is equal to the volume in teaspoons times the density (in g/mL) of the ingredient or material divided by 92.0267.

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

pounds = 5 tsp × 0.7 g/mL92.0267 = 0.038 lb

When to Convert Teaspoons to Pounds

Teaspoons 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 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 volume to weight conversion.

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

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.

What Is a Teaspoon?

The teaspoon is a unit of volume equal to 1/3 of a tablespoon or 1/6 of a fluid ounce.^[3] One teaspoon is equal to approximately 4.929 milliliters, but in nutrition labeling, one teaspoon is equal to exactly 5 milliliters.^[4]

The teaspoon is a US customary unit of volume. Teaspoons can be abbreviated as tsp, and are also sometimes abbreviated as t, ts, or tspn. For example, 1 teaspoon can be written as 1 tsp, 1 t, 1 ts, or 1 tspn.

What Is a Pound?

Pounds are a widely used unit of 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.^[5]

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.^[6]

The pound is a US customary and imperial unit of mass. A pound is sometimes also referred to as a common ounce. Pounds can be abbreviated as lb (plural lbs), and are also sometimes abbreviated as lb_m or #. For example, 1 pound can be written as 1 lb, 1 lb_m, or 1 #, and 2 pounds can be written as 2 lbs.

A pound is also frequently referred to as a unit of weight. While technically, a pound is a measure of mass, and weight is actually a measure of force, the two are equivalent as long as we are performing our calculations on Earth.

For example, an object with a mass of 1 pound weighs 1 pound on Earth, but only weighs one-sixth of that on the moon, yet still has the same mass.
