Pharmacists often prescribe liquid medications in milliliters while patients measure with kitchen tablespoons. The Australian tablespoon being 20 mL versus the US 15 mL is one of the most common sources of recipe confusion in international cooking.

Conversion Tips

One US tablespoon = 14.79 ml (commonly rounded to 15 ml). One Australian tablespoon = 20 ml. This 33% difference is the single most common cause of recipe failures when adapting Australian cookbooks.
Medicine dosing cups are marked in ml. One tablespoon dose = 15 ml, one teaspoon = 5 ml. Always use the ml measurement for medications - kitchen spoons vary significantly in volume.
Three teaspoons equal one tablespoon in both US and metric systems. When halving a recipe that calls for 1 tbsp, use 1.5 tsp rather than estimating half a tablespoon - it is more accurate.
