Tablespoons to Grams Converter
A tablespoon is volume and a gram is weight, so the answer depends on what’s on the spoon: about 14.8 g for water, 14.2 g for butter, 12.5 g for sugar, but only 7.5 g for flour.
Example: with Amount 1 · Direction Tablespoons → grams · Ingredient Water (14.8 g/tbsp) · Custom grams per tablespoon 15 → Converted amount: 14.79 g.

Check it outHow many grams in a tablespoon?
There is no single number, because a tablespoon is a fixed volume (14.79 mL in the US) while grams measure weight. Multiply tablespoons by the ingredient’s grams-per-tablespoon: water ≈ 14.8 g, milk 15.3 g, butter 14.2 g, granulated sugar 12.5 g, olive oil 13.5 g, all-purpose flour just 7.5 g, and dense honey about 21 g. So 1.5 tbsp of butter = 1.5 × 14.2 ≈ 21.3 g, and 2 tbsp of sugar are 25 g.
Going the other way, divide grams by the same density. 20 g to tbsp: 20 ÷ 12.5 = 1.6 tbsp of sugar, but 20 ÷ 7.5 ≈ 2.67 tbsp of flour. 15 g is almost exactly 1 tbsp of water or milk, which is why nutrition math often treats a tablespoon as 15 g — fine for thin liquids, badly wrong for flour or cocoa. When accuracy matters (baking, medication, macros), weigh with a scale instead of scooping.
How it’s calculated
Grams = tablespoons × grams-per-tablespoon; tablespoons = grams ÷ grams-per-tablespoon. 1 US tbsp = 14.7868 mL (NIST), so water is 14.7868 g/tbsp at 1 g/mL. Other reference values follow USDA FoodData Central and King Arthur ingredient weights: butter 14.2, sugar 12.5, flour 7.5 (120 g per 16-tbsp cup), milk 15.3, honey 21, olive oil 13.5 g/tbsp. Weight ounces use 1 oz = 28.3495 g.

Common mistakes
- Using 15 g for every tablespoon — that’s only true for water-thin liquids; a tablespoon of flour is about half that.
- Measuring heaped instead of level spoons: a heaped tablespoon of flour can hold double the weight of a level one.
- Confusing the US tablespoon (14.79 mL) with the Australian one (20 mL) — Australian recipes pack about 35% more into each spoon.
Frequently asked questions
How many grams are in a tablespoon?
It depends on density: about 14.8 g of water, 14.2 g of butter, 12.5 g of granulated sugar, 7.5 g of flour, or 21 g of honey per level US tablespoon.
How many grams is 2 tablespoons of butter?
2 × 14.2 = 28.4 g, which is a quarter of a standard US stick (one stick is 8 tbsp or 113 g).
How many tablespoons is 20 grams?
Divide by the ingredient's g/tbsp: 20 g is 1.6 tbsp of sugar, about 1.35 tbsp of water, or roughly 2.67 tbsp of flour.
Is 1 tablespoon 15 grams?
Only for liquids close to water's density — 1 tbsp of water is 14.79 g, so 15 g is a fair shortcut there. Dry ingredients differ a lot.
How many teaspoons are in a tablespoon?
Exactly 3 US teaspoons; each teaspoon is 4.9289 mL, so a teaspoon of water weighs about 4.9 g.
