What Is a Tablespoons to ML?

The tablespoon is one of the least standardised cooking units. The US tbsp is 14.7868 ml (exactly 1/2 US fluid ounce). The metric tbsp used across most of Europe is rounded to 15 ml. The UK tbsp historically uses 17.7582 ml. Australia is the outlier at 20 ml. Picking the wrong variant scales every spice and seasoning step by 5–35%.

This tool defaults to the US tbsp because US recipes dominate the online corpus, and surfaces the metric (15 ml) and UK (17.7 ml) factors in the helper text. For very small medication doses, use the device that came with the medicine — a kitchen tablespoon is never precise enough.

For cups, teaspoons and ingredient densities in the same recipe, the broader cooking converter is faster.
