Tablespoons to grams converter

Why convert tablespoons to grams?

A tablespoon measures volume; a gram measures mass. A tablespoon of olive oil and a tablespoon of honey fill the same spoon, yet the honey weighs noticeably more. To turn one into the other you need the ingredient’s density — and that is exactly what this converter does for you.

Pick an ingredient, type a number of tablespoons, and the calculator returns the weight in grams. It also works the other way: enter grams and read off how many tablespoons that is. Every result is tailored to the specific ingredient, so you avoid the rounding errors that come from generic “1 tablespoon ≈ 15 g” rules of thumb.

1. Ingredient-aware: Each ingredient carries its own density, so the conversion is accurate.
2. Two-way: Go from tablespoons to grams, or from grams to tablespoons.
3. Different tablespoon sizes: US, international (15 ml), and Australian tablespoons are all supported.
4. Custom ingredients: Not on the list? Enter the density yourself.

Tablespoon sizes

A tablespoon is not a single, universal volume. The converter supports the three most common definitions:

• US tablespoon: 14.7868 ml
• International (metric) tablespoon: 15 ml
• Australian tablespoon: 20 ml

The default is the US tablespoon, the size most American recipes assume.

How density works

The weight of a tablespoon of any ingredient depends on its density. Here are the densities this converter uses for common kitchen ingredients:

Formula

First convert tablespoons to milliliters (1 US tablespoon = 14.7868 ml), then multiply by density to get grams:

$\text{Grams} = \text{Tablespoons} \times 14.7868 \text{ ml} \times \text{Density (g/ml)}$

To go from grams to tablespoons, rearrange the formula:

$\text{Tablespoons} = \frac{\text{Grams}}{14.7868 \text{ ml} \times \text{Density (g/ml)}}$

Convert tablespoons to grams: Examples

The examples below use US tablespoons (14.7868 ml).

Water (density: 1 g/ml)

• 1 tablespoon weighs $1 \times 14.7868 \times 1 = 14.7868 \text{ g}$
• So 14.7868 g of water equals exactly $\frac{14.7868}{14.7868 \times 1} = 1 \text{ tablespoon}$

Sugar (density: 0.845 g/ml)

• 1 tablespoon of granulated sugar weighs $1 \times 14.7868 \times 0.845 = 12.49485 \text{ g}$

Flour (density: 0.593 g/ml)

• 1 tablespoon of all-purpose flour weighs $1 \times 14.7868 \times 0.593 = 8.76857 \text{ g}$
• 2 tablespoons weigh $2 \times 14.7868 \times 0.593 = 17.53714 \text{ g}$

Frequently asked questions

How many grams are in a tablespoon of sugar?

Using the US tablespoon (14.7868 ml) and a sugar density of 0.845 g/ml, one tablespoon of granulated sugar weighs $14.7868 \times 0.845 = 12.49485 \text{ grams}$, roughly 12.5 grams.

How many grams is a tablespoon of flour?

All-purpose flour has a density of about 0.593 g/ml, so one US tablespoon holds $14.7868 \times 0.593 = 8.76857 \text{ grams}$, just under 9 grams.

Why does a tablespoon of one ingredient weigh more than another?

Because of density. A tablespoon always holds the same volume (14.7868 ml for a US tablespoon), but a denser ingredient fits more mass into that space. Honey (1.42 g/ml) is more than twice as dense as flour (0.593 g/ml), so a tablespoon of honey weighs more than twice as much.

What if my ingredient isn’t in the list?

Select “Custom” and type the ingredient’s density. Densities can be found online, in cooking references, or sometimes on the product label.

Does the tablespoon size change the answer?

Yes. A US tablespoon is 14.7868 ml, the international tablespoon is 15 ml, and an Australian tablespoon is 20 ml. An Australian tablespoon of water weighs 20 g while a US tablespoon weighs about 14.79 g. Choose the size your recipe assumes.

How do I convert grams of water to tablespoons?

Water has a density of 1 g/ml, so 1 ml weighs 1 gram. Divide the weight in grams by the tablespoon volume: for a US tablespoon, $\frac{\text{grams}}{14.7868}$. For example, 30 g of water is $\frac{30}{14.7868} \approx 2.03 \text{ tablespoons}$.
