About Tablespoon To Teaspoon Calculator

A UK or US tablespoon is 15 ml and holds three 5 ml teaspoons; the Australian tablespoon is 20 ml and holds four, which is the usual source of confusion. Getting the spoon standard wrong changes a raising agent or salt quantity by a third, which is enough to ruin a bake.
