Tablespoons versus grams in recipes
A tablespoon measures volume and a gram measures weight, so there is no single answer to "how many grams in a tablespoon". The answer is the spoon's volume multiplied by the density of what is in it. A level US tablespoon holds about 14.79 ml. If it is full of water that is 14.8 g, if it is full of runny honey about 20.7 g, and if it is full of flour only about 7.7 g.
That spread is why cooks who care about accuracy, especially for bread and cakes, weigh ingredients rather than scoop them. When a recipe only gives spoons, this converter turns them into a sensible weight.
How to convert tablespoons to grams
- Select the Ingredient.
- Enter the amount in the Convert box and choose US Tablespoons, Imp. Tablespoons, US Teaspoons or Imp. Teaspoons.
- Pick MilliGrams, Grams or KiloGrams in the To menu and read the result.
grams = tablespoons × 14.7868 ml × density (g/ml)For imperial tablespoons use 17.7582 ml. A teaspoon is a third of a tablespoon.

Worked examples
2 tablespoons of water. 2 × 14.7868 × 1.0 = 29.57 g, shown as 30 g.
1 tablespoon of salt. 14.7868 × 1.2 = 17.74 g, shown as 18 g.
3 tablespoons of runny honey. 3 × 14.7868 × 1.4 = 62.1 g, shown as 62 g.
8 tablespoons of granulated sugar. 8 × 14.7868 × 0.895 = 105.9 g. The converter shows 106 g, or 0.106 kg if you pick kilograms.
| US tablespoons | Water (g) | Flour (g) | Granulated sugar (g) | Butter (g) | Honey (g) |

Rounding and accuracy
Tablespoon answers in grams and milligrams are rounded to whole numbers, and kilograms to three decimals. For a single spoonful that means the displayed figure can be off by up to half a gram, as the unrounded column above shows. If you want more detail, choose MilliGrams as the target: one tablespoon of water then reads 14,787 mg.
The densities are typical values. A heaped spoon, packed brown sugar or sifted flour will all differ from the level, loosely filled spoon the figures assume. See the grams to tablespoons converter for the reverse direction, or the tablespoons to cups converter when volume is enough.
