How it's calculated
mL = g ÷ ρ
g = mass in grams, mL = volume in millilitres, ρ = density in g/mL (water ≈ 1). Reverse: g = mL × ρ.
Worked examples
| Ingredient | Density (g/mL) | 100 g equals |
|---|---|---|
| Water | 1.00 | 100 mL |
| Flour | 0.53 | 189 mL |
| Honey | 1.42 | 70 mL |
| Milk | 1.03 | 97 mL |
Common questions
Why isn't grams to mL always one to one?
Only water is one to one. Other ingredients are lighter or heavier per milliliter, so their density changes the volume.
Where do the densities come from?
They are USDA-sourced figures for common food ingredients measured at typical kitchen conditions.
