Select an ingredient and spoon size to estimate grams per spoon or total grams for multiple spoons.
Grams per Spoon Formula
The following formula converts spoonfuls to grams using ingredient density and spoon volume; rearrange to convert grams back to spoons.
\mathrm{grams} = \rho \times V_{\mathrm{spoon}} \times n- US teaspoon = 4.9289 mL
- Metric teaspoon = 5 mL
- US tablespoon = 14.7868 mL
- Metric tablespoon = 15 mL; Australian tablespoon = 20 mL
- Rule of thumb: 1 mL of water ≈ 1 g at room temperature.

How do you convert spoons to grams? Multiply the spoon volume (in mL) by the ingredient’s density (g/mL), then multiply by the number of spoons.
How do you convert grams to spoons? Divide grams by the product of density (g/mL) and the chosen spoon volume (mL).
Example Problem
Convert 2 US tablespoons of honey to grams.
Use the formula: grams = density × spoon volume × spoons.
grams = 1.42 × 14.7868 × 2 ≈ 42.00 g
