Weights, Measurements, and Temperatures

If you need to know how many teaspoons there are in a tablespoon, how many cups there are in a gallon, or convert metric to U.S. standard or vice versa, you've come to the right place.

For precise measurement equivalents of vague, atypical cooking designations, visit our page of pinch, dash and smidgen measurements.

Common measurements and equivalents

1/2 teaspoon = approximately 30-50 drops*
1 teaspoon = 1/3 tablespoon or approx. 60-100 drops
3 teaspoons = 1 tablespoon
1/2 tablespoon = 11/2 teaspoons

4 tablespoons = 1/4 cup or 2 fluid ounces
5 1/3 tablespoons = 1/3 cup or 5 tablespoon + 1 teaspoon
