Convert spoonfuls to grams or grams to spoonfuls using ingredient density and US, metric, or Australian spoon sizes, or calibrate grams per spoon from a measured batch.
Grams per Spoon Formula
The following formula converts spoonfuls to grams using ingredient density and spoon volume; rearrange to convert grams back to spoons.
grams = ρ × Vₛₚₒₒₙ × 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.
Grams per Spoon Conversion Table
| Ingredient | g per US tbsp |
|---|---|
| Water | 14.79 |
| Milk (whole) | 15.23 |
| Olive oil | 13.46 |
| Vegetable oil | 13.60 |
| Sugar (granulated) | 12.57 |
| Brown sugar (packed) | 13.75 |
| Powdered sugar | 7.54 |
| Flour (all-purpose) | 7.84 |
| Flour (whole wheat) | 8.72 |
| Cocoa powder | 5.03 |
| Honey | 21.00 |
| Maple syrup | 20.26 |
| Peanut butter | 15.97 |
| Table salt (1.22 g/mL model) | 18.04 |
| Diamond Crystal kosher salt (King Arthur spoon weight) | 8.00 |
| Baking powder | 11.98 |
| Baking soda | 13.75 |
| Rice (white, uncooked) | 11.68 |
| Rolled oats | 5.03 |
| Butter | 14.20 |
| Yogurt | 15.23 |
| * These illustrative estimates are not universal ingredient constants. Most rows retain the original density models; the named kosher row uses a published spoon weight. Brand, moisture, temperature and packing affect actual weight. Measure a batch when precision matters. | |
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 × 14.78676478125 × 2 ≈ 41.99 g
