A US tablespoon is 14.787 milliliters, or three teaspoons. Australia uses a 20 ml tablespoon and the UK and many metric kitchens use 15 ml, so check the recipe's origin when precision matters.
A US teaspoon is 4.929 milliliters and a third of a tablespoon. Metric recipes often round it to 5 ml. It is the unit for spices, baking powder and vanilla.
One tablespoon equals 3 teaspoons, which makes the tablespoon the larger unit of the two.
