Understanding Tablespoons to Millilitres

One US tablespoon equals exactly 14.7868 millilitres (often rounded to 15ml). This is a fixed conversion because both measure volume. However, UK tablespoons are 17.7582ml, and metric tablespoons are exactly 15ml, so it's important to know which tablespoon measurement you're using. Australian tablespoons are 20ml — significantly larger than US tablespoons.

When to Use Tablespoons to Millilitres

Working with recipes from different countries? Converting tablespoons to millilitres is useful when you need precise liquid measurements. Tablespoons are commonly used in American and British recipes, while millilitres are standard in metric countries. This conversion is essential for adapting recipes across measurement systems.

Practical Tips

This conversion is most useful for liquids like oil, vinegar, or milk, where the measurement is straightforward. It's also helpful when you have measuring spoons marked in tablespoons but need millilitre equivalents, or when following international recipes. For cooking, rounding to 15ml per tablespoon is usually acceptable.

Quick Tips

  • 1 US tablespoon = 14.7868ml (approximately 15ml)
  • UK tablespoons are larger at 17.7582ml
  • Metric tablespoons are exactly 15ml
  • This conversion works perfectly for all liquids since both measure volume

Common Mistakes to Avoid

The most common error is assuming all tablespoons are the same size. US (14.79ml), UK (17.76ml), metric (15ml), and Australian (20ml) tablespoons are all different. Using an Australian tablespoon when a US recipe calls for tablespoons would give you 35% more of each ingredient. Always check which tablespoon system your recipe uses.

When Precision Matters

For most cooking, rounding to 15ml per tablespoon is fine. Precision matters for cocktails, marinades with specific flavour balances, and when scaling recipes significantly. For baking, the tablespoons-to-grams conversion is more important since weight measurements are more accurate for dry ingredients.

Frequently Asked Questions

How many ml in a tablespoon?
It depends on which tablespoon you mean. A US tablespoon is 14.79ml (often rounded to 15ml). A UK tablespoon is 17.76ml. A metric tablespoon is exactly 15ml. An Australian tablespoon is 20ml. Always check which system your recipe uses — the difference can be significant.
Why are Australian tablespoons different from US tablespoons?
Australia adopted a 20ml tablespoon as part of their metric conversion, choosing a round number for convenience. The US retained its traditional tablespoon size (14.79ml). This means Australian recipes calling for tablespoons need adjustment when using US measuring spoons — multiply by 1.35 or measure 20ml per tablespoon.
Should I round 14.79ml to 15ml?
For most cooking purposes, yes. The 1.4% difference rarely affects results. However, for precision work like cocktails or when scaling recipes significantly, use the exact 14.79ml value. Many metric measuring spoons are calibrated to 15ml, which is close enough for everyday cooking.
Is the tablespoons-to-ml conversion the same for all ingredients?
Yes, because both tablespoons and millilitres measure volume. Unlike weight conversions (which depend on density), 1 tablespoon of water, oil, or honey all equal the same number of millilitres. However, they weigh different amounts in grams due to their different densities.
