> Convert tablespoons (US) (tbsp) to millilitres (mL): 1 tablespoon (US) = 14.786765 mL, so multiply by 14.786765 or divide by 0.067628045. Both fields are editable, so you can also type in millilitres and get tablespoons (US) back.

## Inputs

- Tablespoons (US) (tbsp)

## Results

- Millilitres

## Formula

```
1 tbsp = 14.786765 mL
1 mL = 0.067628045 tbsp
mL = tbsp × 14.786765
```

## Explanation

One U.S. tablespoon is 14.79 mL, three teaspoons, or half a fluid ounce. Recipes from the UK and Europe usually assume 15 mL.

### How to use the Tablespoons to mL Converter

- Type the number of tablespoons (US) into the **Tablespoons (US)** field. Decimals such as 0.5 are fine.
- Read the answer in **Millilitres** – it updates as you type, with no button to press.
- To convert the other way, type into **Millilitres** and the tablespoons (US) are recalculated.
- Press **Copy results** to copy both values with the page title, or **Copy link** to share this exact conversion.

This page converts only tbsp ⇄ mL. Need a different unit? Use the general volume converter, where you can choose any “from” and “to” unit.

### How it works

Both units measure volume, so they are always in the same ratio: one tablespoon (US) equals 14.786765 millilitres. The calculator multiplies the number of tablespoons (US) you type by 14.786765 to give millilitres, and when you type into the millilitres field it divides by the same factor to give tablespoons (US). Because the ratio never changes, doubling the tablespoons (US) always doubles the millilitres. Results are calculated at full precision and rounded only for display (up to eight decimal places, with very large or small values shown in scientific notation).

### How to convert tablespoons (US) to millilitres

- Write down the value in tablespoons (US), for example **1 tbsp**.
- Multiply by the conversion factor 14.786765 (because 1 tablespoon (US) = 14.786765 mL).
- 1 × 14.786765 = **14.786765 mL**.
- To go back from millilitres to tablespoons (US), divide by 14.786765 – or multiply by 0.067628045.
