Grams to Milliliters Converter
Convert grams to millilitres for flour, sugar, butter, milk, oil and more, using each ingredient’s own density.
Convert grams and millilitres
Free to use, no sign-up, and everything runs in your browser. This converter is for home cooks and bakers who weigh ingredients in grams but need a volume in millilitres, or the other way round.

Ingredient density reference
Every ingredient in this converter, with its density and what 100 grams looks like in millilitres. The table is built live from the same density values the converter uses.
How grams to millilitres conversion works
Grams measure weight and millilitres measure volume, so you cannot convert one to the other without knowing how dense the ingredient is. Divide grams by density to get millilitres, or multiply millilitres by density to get grams. This tool is free, needs no sign-up, and runs entirely in your browser.
How do you convert grams to millilitres?
Divide the weight in grams by the ingredient’s density in grams per millilitre. For example, flour has a density of about 0.57, so 100 grams of flour is 100 divided by 0.57, which is about 175.4 millilitres. Choose the ingredient above and the calculator does this step for you.
Why can’t you convert grams to millilitres without an ingredient?
Grams measure weight and millilitres measure volume, so the same weight takes up a different amount of space in different ingredients. A gram of honey is much denser than a gram of flour, so 100 grams of honey fills about 70 millilitres while 100 grams of flour fills about 175 millilitres.
How many grams are in a cup of flour?
One US cup of all-purpose flour weighs about 120 grams, according to King Arthur Baking, which lists the weight in its 2024 ingredient weight chart. Because cup sizes and scooping methods vary, weighing flour in grams and converting with this tool gives more reliable baking results than measuring by volume.
Is 1 gram always equal to 1 millilitre?
Only for water, which has a density of 1 gram per millilitre at room temperature. Milk is slightly heavier at 1.03, while oil is lighter at about 0.92, so 100 grams of oil is about 109 millilitres. Always use the ingredient’s own density, not the water shortcut.
How accurate are these conversions?
Densities in this tool are typical values for common ingredients, so results are approximate and can vary with brand, temperature and how tightly a dry ingredient is packed. For everyday cooking and baking they are close enough, but for laboratory work or precise nutrition labels use a measured density for your exact ingredient.
Which ingredients are hardest to convert?
Powders and flakes are the hardest, because how you scoop and pack them changes their density. A cup of flour can weigh anywhere from 120 to 150 grams depending on whether it is spooned in or scooped straight from the bag. Liquids such as milk, oil and honey are far more consistent, because their density barely changes.
Frequently asked questions
How many ml is 100 g of flour?
100 grams of all-purpose flour is about 175.4 millilitres, because flour has a density of about 0.57 grams per millilitre. Divide 100 by 0.57 to get 175.44 ml.
How many grams is 250 ml of milk?
250 millilitres of milk weighs about 257.5 grams, because milk has a density of about 1.03 grams per millilitre. Multiply 250 by 1.03.
How do I convert grams to ml for butter?
Butter has a density of about 0.96 grams per millilitre, so divide grams by 0.96. For example, 100 grams of butter is about 104.2 ml, and one US stick of butter (113 g) is about 118 ml.
How many ml is 100 g of sugar?
100 grams of granulated sugar is about 117.6 millilitres, using a density of 0.85 grams per millilitre. Brown sugar packs more tightly, so its density is a little higher and the same weight fills a little less space.
Why do different ingredients give different answers?
Because density differs. One gram of honey takes up less space than one gram of flour, so the same weight converts to a different volume. That is why this converter asks which ingredient you are measuring.
Can I convert ml back to grams?
Yes. Switch the direction to millilitres to grams, enter the volume, and the calculator multiplies by the ingredient’s density. For example, 250 ml of milk is 257.5 grams.
Is this converter free?
Yes. It is free, needs no sign-up, and runs entirely in your browser. Your numbers are never uploaded or stored.
