A teaspoon is a small unit of volume commonly used in cooking and baking. It equals 1/3 of a tablespoon or 1/6 of a fluid ounce. One teaspoon is approximately 4.929 mL, though nutrition labels often round it to exactly 5 mL.
A cup is a unit of volume used primarily in cooking in the United States. One US customary cup equals 8 fluid ounces, 16 tablespoons, or 48 teaspoons. It is approximately 236.6 milliliters.
There are exactly 48 teaspoons in one US customary cup. This is the conversion factor used to convert between these two volume units.
A half cup equals 24 teaspoons. Since a full cup contains 48 teaspoons, simply divide by 2 to get the teaspoon equivalent for half a cup.
A quarter cup equals 12 teaspoons. You can verify this with the formula: 48 teaspoons per cup × 0.25 = 12 teaspoons.
Not exactly. The US teaspoon is approximately 4.929 mL, while the metric teaspoon used in Australia and other countries is exactly 5 mL. For everyday cooking the difference is negligible, but it can matter in precise scientific or nutritional contexts.
Yes, teaspoons and cups measure volume regardless of whether the ingredient is dry or liquid. However, keep in mind that the weight of a teaspoon or cup of an ingredient will vary depending on its density — volume and weight are not the same thing.
