Common questions
How many mL in a tablespoon?
It depends on the standard. A US tablespoon is 14.79 mL, a metric one is 15 mL, and an Australian one is 20 mL.
Does the difference matter in baking?
Usually a little, but across many spoonfuls the Australian 20 mL spoon can add up to a noticeable amount, so match the recipe's origin when you can.
