Cooking Weight Converter
Convert cooking ingredients between weight and volume, allowing for each ingredient's density.
Grams to millilitres, ingredient by ingredient
Converting a cooking ingredient between weight and volume — grams to millilitres or cups — is not one fixed sum, because different ingredients have different densities. A hundred grams of flour and a hundred grams of honey take up very different amounts of space. This converts by ingredient, using each one's typical density, so the weight-to-volume conversion is right rather than a generic guess.
Choose the ingredient, enter a weight or volume, and get the other.
Why density is the whole point
This is the crux that catches people out: weight and volume only convert cleanly for water, where a millilitre is a gram. Everything else has its own density, so a recipe that gives flour in grams but sugar in cups needs each converted with its own factor. Getting this right matters most in baking, where proportions are precise. Where a recipe mixes weight and volume measures, converting each ingredient properly, rather than assuming one factor fits all, is what keeps the recipe working as intended.
Common questions
Why does the ingredient matter for weight-to-volume?
Because ingredients have different densities — the same weight of flour and honey take up very different volumes — so each needs its own factor.
Does one gram always equal one millilitre?
Only for water. Every other ingredient has its own density, which is why the conversion is done per ingredient.
