The US tablespoon is defined as exactly 15 ml — equivalent to 3 teaspoons, half a fluid ounce, or 1/16 of a cup. This clean relationship makes the tablespoon one of the easier cooking measurements to convert to metric.
However, there is an important international difference: the Australian metric tablespoon is 20 ml, not 15 ml. Recipes from Australia, New Zealand, and some other countries use the 20 ml tablespoon. If you are following an Australian recipe, multiply tablespoons by 20 instead of 15. This converter uses the US/UK standard of 15 ml per tablespoon.
For small quantities in baking (baking powder, yeast, spices), the tablespoon is the practical measuring unit. For liquids like oil, vanilla extract, or soy sauce, tablespoons are common in US recipes while European recipes often specify millilitres directly.
