Grams to mL Converter
Convert grams to millilitres (and back) for water, milk, oil, flour, sugar, honey and other ingredients.
About the Grams to mL Converter
Grams measure weight and millilitres measure volume, so the conversion depends on density. Water is 1 g per mL; honey is heavier (1.42 g/mL); flour is light and fluffy (about 0.51 g/mL when spooned into a cup). Dry-ingredient densities here follow King Arthur Baking's standard cup weights; liquids use measured densities. Weighing is always more accurate than measuring by volume.
The formula
mL = grams ÷ density (g/mL)

Worked example
Example: Millilitres = 220 mL
- Inputs: Ingredient: Water; Convert: Grams → mL; Amount: 220.
- Formula: mL = grams ÷ density (g/mL)
- Result: Millilitres = 220 mL
Questions people ask
Is 100 g of flour 100 mL?
No, about 200 mL (0.83 cup).
Why does my recipe differ?
Flour measured by scooping is packed and heavier than spooned flour.
