What is a tablespoon?
A tablespoon is a unit of volume commonly used in cooking recipes to measure both liquid and dry ingredients. Among culinary measurements, the tablespoon often stands out due to its frequent use in both home kitchens and professional settings. One significant detail to understand is that tablespoons are not standardized globally, hence different regions may have slightly different measurements.
Different types of tablespoons
-
Metric tablespoon (15 ml): Often used in countries that follow the metric system, such as the UK, Canada, and Australia. The metric tablespoon is standardized at 15 milliliters.
-
United States tablespoon (14.79 ml): In the United States, a tablespoon is slightly smaller and equals approximately 14.79 ml or 0.5 liquid ounce.
-
Australian tablespoon (20 ml): In Australia, a metric tablespoon is used, which is unique and equals 20 ml.
Understanding these distinctions is crucial for accurate conversions, especially when recipes cater to international audiences or require meticulous measurements.

Interesting examples
Baking a cake
Consider a recipe that calls for 2 tbsp of vanilla extract. Depending on the standard, this equates to:
- Metric: 2 tbsp x 15 ml = 30 ml
- US: 2 tbsp x 14.79 ml = 29.58 ml
- Australian: 2 tbsp x 20 ml = 40 ml If you are using a recipe from an international website, be sure to identify which standard of tablespoon is used to ensure the precise amount of vanilla extract flavor.
Mixing a salad dressing
Creating a salad dressing might involve a 1.5 tablespoon of olive oil and vinegar. For a balanced dressing:
- Metric (Oil): 1.5 tbsp olive oil x 15 ml = 22.5 ml
- US (Vinegar): 1.5 tbsp vinegar x 14.79 ml = 22.185 ml
The slight difference may not seem significant for larger quantities, but it becomes evident in recipes with smaller serving sizes.

Notes
- Rounded measurements: Due to the nature of tablespoon measurements and their use in cooking, rounding is commonly practiced. Be aware of the precision level required for certain recipes versus common round number usage.
- Ingredient density: The conversion works flawlessly for liquids; however, for solid ingredients, converting to milliliters can be affected by ingredient density and pack method.
- International recipes: Always understand the source of a recipe and any specific measurement standards indicated or implied.
Frequently asked questions
How to determine ml in tablespoons?
For metric tablespoons, multiply the number of tablespoons by 15. For US tablespoons, multiply by 14.79. For Australian tablespoons, multiply by 20.
Why are tablespoon sizes different between countries?
