Milligrams to Tablespoons Converter

The Mg to Tablespoon Converter converts between milligrams (mass) and tablespoons (volume). Kitchen recipes often list small ingredient amounts in milligrams for supplements or precise baking, while tablespoons are a common US volume measure equal to $15\ mL$.

Conversion Formula

To convert milligrams to tablespoons:

$$\text{tbsp} = \frac{mg}{\rho \times 15 \times 1{,}000}$$

To convert tablespoons to milligrams:

$$mg = \text{tbsp} \times 15 \times \rho \times 1{,}000$$

Where $\rho$ is ingredient density in $g/mL$. For honey at $1.42\ g/mL$, one tablespoon weighs about $21.3$ grams or $21{,}300$ mg.
