Milliliters to Grams Converter
Choose the ingredient, enter an amount in milliliters or liters and read the weight in milligrams, grams or kilograms. Each ingredient has its own density, so 100 ml of honey and 100 ml of flour weigh very different amounts.

Why milliliters and grams are not the same
A milliliter measures how much space something fills. A gram measures how much matter it contains. The two numbers match only for water, because the gram was originally defined from the mass of a small cube of water: one milliliter of water weighs about one gram.
Every other ingredient packs a different amount of mass into the same space. Oil is lighter than water, which is why it floats. Honey and salt are heavier. Flour and ground almonds are mostly air between tiny particles, so a milliliter of them weighs about half as much as a milliliter of water. That ratio of weight to volume is called density, and it is what this converter uses.
How to convert milliliters to grams
- Pick the Ingredient from the list.
- Enter the amount and choose MilliLiters or Liters as the starting unit.
- Choose MilliGrams, Grams or KiloGrams in the To menu and read the result below.
grams = milliliters × density (g/ml)Density in g/ml equals kg per cubic meter divided by 1,000.
For liters, multiply by 1,000 first. To express the answer in kilograms divide the grams by 1,000, and for milligrams multiply them by 1,000.
Densities used by the converter
| Ingredient | Density (g/ml) | 100 ml weighs (g) |
|---|---|---|
| Water | 1 | 100 |
| Flour | 0.52 | 52 |
| Caster Sugar | 0.84 | 84 |
| Granulated Sugar | 0.895 | 89.5 |
| Icing / Powdered Sugar | 0.62 | 62 |
| Brown Sugar | 0.845 | 84.5 |
| Salt | 1.2 | 120 |
| Butter | 0.959 | 95.9 |
| Vegetable Oil | 0.918 | 91.8 |
| Milk | 1.037 | 103.7 |
| Runny Honey | 1.4 | 140 |
| Maple Syrup | 1.333 | 133.3 |
| Creams | 1 | 100 |
| Rice | 0.8 | 80 |
| Ground Almonds | 0.48 | 48 |
| Chia Seeds | 0.71 | 71 |
| Cocoa Powder | 0.465 | 46.5 |
| Chocolate Chips | 0.75 | 75 |
| Custard | 1.1 | 110 |
Worked examples
250 ml of runny honey. 250 × 1.4 = 350 g. Honey is heavy, so a quarter liter weighs more than a third of a kilogram.
100 ml of vegetable oil. 100 × 0.918 = 91.8 g, about 8% less than the same volume of water.
500 ml of flour. 500 × 0.52 = 260 g. Half a liter of water would be almost twice as heavy.
1 liter of milk. 1,000 × 1.037 = 1,037 g, which the converter shows as 1.037 kg when you pick kilograms.
| Milliliters | Water (g) | Flour (g) | Granulated sugar (g) | Butter (g) | Honey (g) |
|---|---|---|---|---|---|
| 15 | 15 | 7.8 | 13.425 | 14.385 | 21 |
| 30 | 30 | 15.6 | 26.85 | 28.77 | 42 |
| 60 | 60 | 31.2 | 53.7 | 57.54 | 84 |
| 125 | 125 | 65 | 111.875 | 119.875 | 175 |
| 250 | 250 | 130 | 223.75 | 239.75 | 350 |
| 500 | 500 | 260 | 447.5 | 479.5 | 700 |
Accuracy and rounding
The built-in densities are sensible averages, not laboratory values. Flour that has been sifted or packed can differ from the figure by a fifth either way, brown sugar changes with how firmly it is pressed, and honey is thicker when cold. Treat the result as an estimate for planning, and weigh the ingredients that matter most when you bake.
Rounding depends on the units. Starting from milliliters, grams are shown to four decimals and milligrams to three. Starting from liters, grams and milligrams are rounded to whole numbers. Kilograms always show three decimals. For the reverse job use the grams to milliliters converter.
Frequently asked questions
How many grams is 100 ml of water?
100 ml of water weighs about 100 grams, because one milliliter of water is close to one gram.
How many grams is 100 ml of milk?
Milk is slightly denser than water. With the density used here (1.037 g/ml), 100 ml of milk is 103.7 g.
Is 1 ml always equal to 1 gram?
No. That is true only for water. A milliliter of oil weighs less than a gram, and a milliliter of honey or salt weighs more.
Why does 100 ml of flour weigh so little?
Flour holds a lot of air between its particles. At 0.52 g/ml, 100 ml of flour is 52 g, roughly half the weight of 100 ml of water.
What if my ingredient is not in the list?
Choose the ingredient whose density is closest to yours, or multiply the volume in ml by the density of your ingredient in g/ml yourself.
