If you are measuring liquids, 1 cup is 48 tablespoons.
If you are measuring dry goods such as flour or sugar there are 3 different ways to use the various sizes of spoon measurements - level, rounded and heaped.
Level = filled level to the rim of the spoon
Rounded = filled such that there is as much above the rim of the spoon as there is below it.
Heaped = as much as you can possibly get on the spoon
Using this as a reference 1 cup would be the equivalent of -
48 level teaspoons
24 rounded teaspoons
15 to 18 heaped teaspoons, depending on the ingredient
