Determine the number of teaspoons you need to convert to drops.
Determine the kind of teaspoon you are converting from. If you don't know, you probably want to use U.S. teaspoons.
Multiply the number of teaspoons by the correct conversion factor. The number of drops in a U.S. teaspoon is 98.5784322, but these numbers are usually rounded up to two places beyond the decimal point, so you would use 98.58. The U.K. teaspoon equals 118.39 drops, and the metric teaspoon equals 100 drops. If you have 8 tsp. to convert, you would perform the following calculations: 8 x 98.58, 8 x 118.39 and 8 x 100. Your answers for the corresponding teaspoon measurements would be 788.64 drops, 947.12 drops and 800 drops.
