## Default answer

Example with the default inputs (Grams (g) 1, Ingredient Water at 4 °C, 236.582 g per cup): 1 g = 0.06763 tbsp (Water at 4 °C, 236.582 g per cup).

## Inputs

| Key | Label | Description |
| --- | --- | --- |
| value | Grams (g) | The amount in grams to convert. |
| result | Tablespoons (tbsp) | The same amount in tablespoons. |
| ingredient | Ingredient | What you are measuring. A cup of flour weighs less than a cup of water. |

## Outputs

| Key | Label | Description |
| --- | --- | --- |
| value | Grams (g) | The amount in grams to convert. |
| result | Tablespoons (tbsp) | The amount in tablespoons. |

## Method

tablespoons = grams ÷ 236.582321794 × 16, where grams per cup depends on the ingredient (water at 4 °C: 236.582 g)

## Assumptions

- Grams per cup are USDA FoodData Central (SR Legacy) portion weights for one level US cup (8 US fluid ounces): all-purpose flour 125 g (FDC 168894), granulated sugar 200 g (FDC 169655), brown sugar, packed 220 g (FDC 168833), powdered sugar, unsifted 120 g (FDC 169656), whole milk 244 g (FDC 171265), butter 227 g (FDC 173410), olive oil 216 g (FDC 171413), honey 339 g (FDC 169640), white rice, uncooked 185 g (FDC 169756).
- Water is pure water: 0.999975 kg per liter at 4 °C and 0.998207 kg per liter at 20 °C, from the Tanaka et al. (2001) density formula.
- How you fill the tablespoon changes the weight: packed, sifted, or scooped flour can differ by 20% or more.
- A US cup is 16 tablespoons or 48 teaspoons, so a tablespoon holds 1/16 and a teaspoon 1/48 of a cup.
- Exact on the typed decimals: at most 6 decimal places (6 significant digits below 0.0001), rounded half up; an answer of 1 billion or more shows at most 15 significant digits.

## Worked examples

1. value = 100, ingredient = water gives result = 6.762974. Source: Density of pure water from Tanaka et al. (2001), Metrologia 38, 301: 999.9749 kg/m³ at 4 °C, 998.2067 kg/m³ at 20 °C, as 0.999975 kg per liter.
2. value = 125, ingredient = flour gives result = 16. Source: USDA FoodData Central SR Legacy 168894: 1 cup = 125 g.

## FAQ

### How many tablespoons are in 100 grams?

It depends on the ingredient, because a weight does not fix the volume. 100 g is about, in tablespoons: all-purpose flour 12.8; granulated sugar 8; brown sugar, packed 7.273; powdered sugar, unsifted 13.33; water at 4 °C 6.763; water at 20 °C 6.775; whole milk 6.557; butter 7.048; olive oil 7.407; honey 4.72; white rice, uncooked 8.649.

### How do I convert grams to tablespoons?

tablespoons = grams ÷ 236.582321794 × 16, where grams per cup depends on the ingredient (water at 4 °C: 236.582 g). For example, 100 g of water at 4 °C is 6.762974 tablespoons.

### How many grams are in a tablespoon?

It depends on the ingredient. A level US tablespoon is 1/16 of a US cup, so it holds about: all-purpose flour 7.813 g; granulated sugar 12.5 g; brown sugar, packed 13.75 g; powdered sugar, unsifted 7.5 g; water at 4 °C 14.79 g; water at 20 °C 14.76 g; whole milk 15.25 g; butter 14.19 g; olive oil 13.5 g; honey 21.19 g; white rice, uncooked 11.56 g.

### Are USDA's own tablespoon weights the same?

Close. This page divides the USDA cup weight by 16. USDA also lists some spoons measured on their own: honey 21 g a tablespoon (339 ÷ 16 = 21.19 g) and butter 14.2 g (227 ÷ 16 = 14.19 g).

### Is a tablespoon 15 mL?

A US tablespoon is 1/2 US fluid ounce, 14.786765 mL. Metric spoons hold 15 mL, as NIST's metric kitchen guide counts it.
