UK Spoon Sizes Explained

The United Kingdom uses a straightforward metric system for spoon measurements in cooking:

  • 1 teaspoon (tsp) = 5ml — the small spoon used for stirring tea or measuring small amounts of spices, baking powder, or vanilla extract
  • 1 dessertspoon (dsp) = 10ml — a measurement unique to UK cooking, falling between a teaspoon and tablespoon. Less common in modern recipes but still appears in older British cookbooks
  • 1 tablespoon (tbsp) = 15ml — the large serving spoon used for measuring larger quantities of flour, sugar, butter, or liquids

All UK spoon measures are for level spoonfuls unless otherwise stated. "A heaped tablespoon" means filled generously above the rim; "a rounded tablespoon" means a slight dome above the rim. In recipes, assume level unless specified. A level tablespoon is important for accuracy, particularly with leavening agents like baking powder and bicarbonate of soda.

UK vs US Tablespoon: Is There a Difference?

The UK tablespoon is 15ml, while the US tablespoon is 14.79ml. The difference is just 0.21ml — less than 1.5%. For home baking purposes, this is entirely negligible. You do not need to adjust measurements when using a US recipe with UK spoons. The difference only becomes relevant if you are converting very large quantities (dozens of tablespoons) or working in a professional kitchen requiring extreme precision.

Australian tablespoons are 20ml — significantly larger than both UK and US versions. If following an Australian recipe, note that their tablespoon calls for more of the ingredient. Our calculator defaults to UK/US (15ml) but you can adjust by using 1.33 tablespoons for each Australian tablespoon called for.

Tablespoon to Grams: Complete Ingredient Table

All values are for 1 level tablespoon (15ml) using UK measurements. Teaspoon = ⅓ of these values, dessertspoon = ⅔ of these values.

Practical Guidance for Spoon Measurements

When Precision Really Matters

Baking powder and bicarbonate of soda are the most critical ingredients to measure accurately. These leavening agents have powerful effects in small quantities. Too much causes excessive rising followed by collapse; too little leaves baked goods dense and flat. Always use a level teaspoon or tablespoon, and consider weighing these on a scale for very precise results.

Salt is deceptively heavy — 1 tablespoon of fine salt weighs 18g, while 1 tablespoon of flaky sea salt (like Maldon) weighs far less due to its irregular crystal structure and air gaps. When a recipe specifies "1 tsp fine salt" and you use flaky salt, your dish may be undersalted. Conversely, replacing flaky salt with fine salt could oversalt it.

Heaped vs Level Measurements

UK recipes assume level spoonfuls unless stated otherwise. In practice:

  • Level tablespoon: Fill the spoon and use a straight edge (knife back) to remove the excess. This is the standard.
  • Rounded tablespoon: Fill the spoon so there is a small dome of ingredient above the rim. Approximately 1.3× a level tablespoon.
  • Heaped tablespoon: Fill as much as the spoon can hold without spilling. Approximately 1.5–2× a level tablespoon, depending on the ingredient.

Oil and Liquids: Volume vs Weight

For water and most thin liquids, 1ml = 1g, so a tablespoon of water = 15ml = 15g. For oils, the density is slightly less than water (approximately 0.92 g/ml for vegetable oil), so 1 tablespoon of oil ≈ 14g. For honey and syrups, density exceeds water — 1 tablespoon of honey ≈ 21g due to its concentrated sugar content.

Converting Between Spoon Types

Use these relationships: 3 teaspoons = 1 tablespoon. 1.5 dessertspoons = 1 tablespoon. 2 teaspoons = 1 dessertspoon. When a recipe calls for "1 dessertspoon" and you do not have one, use 2 level teaspoons or approximately ⅔ of a level tablespoon.

Frequently Asked Questions

How many grams is 1 tablespoon of flour?
1 tablespoon of plain or all-purpose flour equals approximately 8g. Self-raising flour is also about 8g per tablespoon. These values are for level tablespoons — a heaped tablespoon can be 10–12g. This applies whether using UK (15ml) or US (14.79ml) tablespoon measures, as the difference is negligible.
How many grams is 1 tablespoon of sugar?
1 level tablespoon of granulated or caster sugar equals approximately 12g. Icing sugar is lighter at about 8g per tablespoon due to its fine powder texture. Brown sugar (lightly packed) is approximately 12g. Demerara sugar's coarser crystals pack slightly more densely, giving about 13g per tablespoon.
Is a UK tablespoon the same as a US tablespoon?
A UK tablespoon = 15ml; a US tablespoon = 14.79ml. The difference (0.21ml, under 1.5%) is entirely negligible for home baking and cooking. You can use UK and US spoon measures interchangeably. Note that Australian tablespoons are 20ml — if following an Australian recipe, multiply tablespoon quantities by 1.33 to get the UK equivalent.
How many grams is 1 tablespoon of butter?
1 tablespoon of butter equals approximately 14g (14.175g precisely). This is about 0.5 oz. If a recipe calls for "3 tablespoons of butter," that is approximately 42g. This is helpful when you need a small amount of butter and do not want to weigh the full block.
How many grams is 1 tablespoon of honey?
1 tablespoon of honey equals approximately 21g. Honey is notably dense — much heavier than flour or sugar per tablespoon — because its high sugar content gives it a density of about 1.4 g/ml. Golden syrup and treacle have similar weights. Maple syrup is slightly lighter at about 20g per tablespoon.
How many teaspoons are in a tablespoon?
There are exactly 3 teaspoons in 1 tablespoon. A UK teaspoon = 5ml; a UK tablespoon = 15ml. A dessertspoon = 10ml = 2 teaspoons. This relationship is consistent between UK and US measurements. If you do not have a tablespoon measure, use 3 level teaspoons as an accurate substitute.
How many grams is 1 tablespoon of salt?
1 tablespoon of fine table salt weighs approximately 18g. However, this varies dramatically by salt type: flaky sea salt (Maldon-style) may weigh only 8–10g per tablespoon because of the irregular flake structure and air gaps. When converting between fine salt and flaky salt, use weight (grams) rather than volume (tablespoons) for consistency.
What is a dessertspoon?
A dessertspoon (dsp) is a UK measurement equal to 10ml. It is twice a teaspoon and two-thirds of a tablespoon. It appears in older British and Irish recipes (pre-1970s particularly) and is less common in modern recipe writing. If your recipe calls for "1 dessertspoon," use 2 level teaspoons or ⅔ of a tablespoon as a substitute.
