Tablespoons and Teaspoons to Grams for Common Ingredients
Gram weights for a tablespoon and teaspoon of butter, sugar, flour, salt, oil, and honey, plus the difference between US, metric, and Australian tablespoon sizes.
Tablespoons and teaspoons feel like the most exact tools in your kitchen drawer — a level tablespoon should be a level tablespoon, right? — but the gram weight behind that spoonful still depends entirely on the ingredient's density, exactly like cups do, just at a smaller scale where the errors matter less in absolute terms but can still shift a recipe. On top of that, 'a tablespoon' isn't even one universal volume: the US tablespoon (14.79ml, rounded to 15ml) is smaller than the Australian tablespoon (20ml), a difference that trips up anyone following a recipe written in the other system. This guide gives you gram weights for the ingredients you're most likely to measure by spoon, plus the international tablespoon sizing you need to know when a recipe's origin isn't obvious.
US tablespoon = 15ml, US teaspoon = 5ml, 3 tsp = 1 tbsp
The US tablespoon is defined as 14.79ml, universally rounded to 15ml for cooking purposes, and it always equals exactly 3 teaspoons of 5ml each — this 3:1 ratio holds regardless of what you're measuring, since it's a fixed volume relationship, not an ingredient-dependent one. This is the baseline assumed by virtually all US and most internationally-published English-language recipes unless stated otherwise.
Butter, sugar, and salt by tablespoon
1 tablespoon of butter weighs 14g (matching the printed markings on a US butter stick, since 8 tbsp = 113g/stick); 1 tablespoon of granulated sugar weighs 12.5g; 1 tablespoon of fine table salt weighs about 18g, notably heavier than sugar because salt crystals are denser and pack more tightly, while coarse kosher salt is lighter by volume at roughly 10-15g per tablespoon depending on brand, since its larger flakes leave more air between them.
💡 Suggerimento: Kosher salt brands vary significantly in crystal size — Diamond Crystal weighs about 2.8g/tsp while Morton weighs about 5g/tsp for the same volume. If a recipe doesn't specify the brand, err toward Diamond Crystal's lighter weight and adjust by taste.
Flour and cocoa powder by tablespoon
1 tablespoon of all-purpose flour (spooned and leveled) weighs about 7.5g, consistent with the 120g-per-cup reference divided across 16 tablespoons per cup. Cocoa powder is lighter and airier, weighing about 5-6g per tablespoon, or 40-50g per cup — this matters for recipes that call for a few tablespoons of cocoa as a thickener or flavoring rather than a full cup, where the smaller weight difference from flour is easy to miscalculate if you assume the two powders weigh the same.
Honey, oil, and other liquids by tablespoon
1 tablespoon of honey weighs about 21g (honey is denser than water, roughly 1.4g/ml); 1 tablespoon of vegetable or olive oil weighs about 13.5g (oil is slightly less dense than water, about 0.92g/ml); 1 tablespoon of water weighs almost exactly 15g, since water's density is defined as 1g/ml. These density differences are why a recipe that swaps honey for oil (or vice versa) 1:1 by volume is not swapping the same weight or the same amount of moisture into the batter.
💡 Suggerimento: To keep sticky ingredients like honey or molasses from clinging to the spoon and under-measuring, lightly coat the measuring spoon with a neutral oil or nonstick spray first — it slides out clean and you get the full intended weight.
Metric vs. Australian tablespoons — the 15ml vs 20ml trap
Nearly every English-speaking country uses a 15ml tablespoon — the US, UK, Canada — but Australia and New Zealand traditionally use a 20ml tablespoon, about a third larger. This means an Australian recipe calling for '2 tablespoons oil' means 40ml, not the 30ml a US cook would assume, a meaningful difference in a small-batch recipe like a salad dressing or a single-serving baked good. The teaspoon size, however, stays consistent at 5ml across all these countries — only the tablespoon changes.
💡 Suggerimento: If a recipe's country of origin isn't stated but the ingredient amounts feel oddly large for tablespoon measurements, check whether it might be Australian — the 20ml tablespoon is the most common source of that discrepancy.
Why teaspoon measurements matter more for spices and leaveners
Small-volume ingredients like baking soda, baking powder, salt, and spices are measured by teaspoon rather than tablespoon precisely because their effect on a recipe is disproportionate to their weight — 1 extra teaspoon of baking soda (about 4.6g) can make a cake taste metallic or rise unevenly, while the same volume error in flour would be imperceptible. For these ingredients, use dedicated measuring spoons rather than a random kitchen spoon, and level them the same way you would a cup — mounded teaspoons of baking powder can easily be 20-30% over the intended amount.
Domande frequenti
How many grams is a tablespoon of butter?
1 tablespoon of butter weighs 14 grams, which matches the tablespoon markings printed on US butter stick wrappers — 8 tablespoons make up one 113g stick.
Is an Australian tablespoon the same as a US tablespoon?
No. A US, UK, or Canadian tablespoon is 15ml, but an Australian or New Zealand tablespoon is 20ml, about a third larger. If you're following an Australian recipe with a US measuring spoon, you'll under-measure by 25% unless you adjust.
How many teaspoons are in a tablespoon?
3 teaspoons equal 1 tablespoon, and this ratio is constant regardless of country or ingredient — it's a fixed volume relationship (5ml × 3 = 15ml for the standard US/UK tablespoon).
How many grams is a tablespoon of honey?
1 tablespoon of honey weighs about 21 grams, heavier than water's 15g per tablespoon because honey is denser (roughly 1.4g per ml) due to its high sugar concentration and low water content.
Why does a tablespoon of salt weigh more than a tablespoon of sugar?
Fine table salt crystals are smaller and denser than granulated sugar crystals, so they pack more tightly into the same volume — a tablespoon of table salt weighs about 18g versus sugar's 12.5g. Coarse kosher salt, with larger flakes, weighs noticeably less per tablespoon than fine table salt.
Tablespoon and teaspoon measurements are more forgiving than cups simply because the absolute gram errors are smaller, but the same density-dependent logic applies: a tablespoon of honey, oil, flour, and salt are all meaningfully different weights despite occupying the same volume. Know the standout numbers — butter at 14g/tbsp, sugar at 12.5g/tbsp, honey at 21g/tbsp — and always double-check whether a recipe is using the 15ml US/UK tablespoon or the 20ml Australian one before you measure.
