What is tablespoon?
A tablespoon is a small cooking measurement used for ingredients such as oil, sauce, sugar, spices and liquids. In practical UK kitchen maths, 1 tablespoon is usually treated as 15ml.
A tablespoon is a kitchen measure used for small ingredient amounts. It is commonly used in recipes for liquids, oils, sauces, spices, sugar and other ingredients that are too small for cups but larger than teaspoons.
For most cooking conversions, 1 tablespoon is treated as 15ml, which is the same as 3 teaspoons. If you are converting tablespoons to grams, the answer depends on the ingredient because millilitres measure volume and grams measure weight.
Why tablespoons matter in recipes
Tablespoons are used when a recipe needs a small but still noticeable amount of an ingredient. They are especially common for oil, butter, milk, vinegar, sauces, honey, spices and flavourings.
They also matter when using a recipe scaler, because scaling small measurements can create awkward results. For example, 1 tablespoon scaled by 1.5 becomes 1.5 tablespoons, which may be easier to measure as 1 tablespoon plus 1 1/2 teaspoons.

Common tablespoon equivalents
For practical cooking, these are the most useful tablespoon conversions to remember.
| Measurement | Equivalent | Kitchen note |
|---|---|---|
| 1 tablespoon | 15ml | Common cooking conversion. |
| 1 tablespoon | 3 teaspoons | Useful when measuring smaller amounts. |
| 1/2 tablespoon | 7.5ml | Often measured as 1 1/2 teaspoons. |
| 2 tablespoons | 30ml | Useful for sauces, oil and liquids. |
| 4 tablespoons | 60ml | About 1/4 cup if using a 240ml cup estimate. |
Tablespoons to grams depends on the ingredient
A tablespoon is a volume measurement. Grams are a weight measurement. That means there is no single exact tablespoon-to-grams answer for every ingredient.
If a recipe gives tablespoons but you need grams, use the ingredient setting in the cooking unit converter rather than assuming every ingredient weighs the same.
Tablespoons when scaling recipes
When you scale a recipe up or down, tablespoon amounts are multiplied by the same scale factor as the rest of the ingredients.
scaled tablespoons = original tablespoons × scale factorFor example, if a recipe uses 2 tablespoons of oil and you scale it from 4 servings to 6 servings, the scale factor is 6 ÷ 4 = 1.5. The new amount is 2 × 1.5 = 3 tablespoons.
| Original amount | Scale factor | Scaled amount |
|---|---|---|
| 1 tablespoon | 2 | 2 tablespoons |
| 2 tablespoons | 1.5 | 3 tablespoons |
| 1 tablespoon | 0.5 | 1/2 tablespoon, or 1 1/2 teaspoons |
Practical rounding for tablespoons
Tablespoon results can become awkward when a recipe is scaled. A kitchen-friendly result is often better than a long decimal.
- Round 1.5 tablespoons to 1 tablespoon plus 1 1/2 teaspoons.
- Round 0.5 tablespoon to 1 1/2 teaspoons.
- For strong flavours such as chilli, salt or spices, scale carefully and taste as you go.
- For baking powder, yeast and similar ingredients, avoid heavy rounding unless you understand the recipe.
Tablespoon vs teaspoon
A tablespoon is larger than a teaspoon. In common cooking conversions, 1 tablespoon equals 3 teaspoons.
| Unit | Common abbreviation | Approximate ml |
|---|---|---|
| Tablespoon | tbsp | 15ml |
| Teaspoon | tsp | 5ml |
Always check whether a recipe uses “tbsp” or “tsp”, because mixing them up can triple or reduce an ingredient amount.
