1 Cup [US] = 16 Tablespoons [US]
1 Cup [Metric] = 14 Tablespoons [UK]
There are 16 tablespoons in a cup, because from the largest to the smallest units between cup and tablespoon, there are 8 ounces in a cup and 2 tablespoons in an ounce, that makes 8 * 2 = 16 tablespoons in a cup.
For example, to find out how many tablespoons there are in a cup and a half, multiply the number of cups by the conversion factor, that makes 1.5 c * 16 = 24 tablespoons in 1.5 cups.
