Grams to ML Converter: gm to ml for Water, Milk, Flour and More

Last updated October 10, 2026

To convert grams to ml, divide the grams by the density of the ingredient. For water, 1 gram takes up about 1 ml, so 100 grams of water is 100 ml. Every other ingredient is different, because a gram measures weight and a milliliter measures space. Flour is light and airy, so 100 grams fills 197 ml, while honey is heavy, so 100 grams fills only 70 ml.

Grams to ML Calculator

Pick your ingredient, type the grams, and read the answer in ml. You can also switch direction to turn ml into grams. The result shows US cups and tablespoons too, so you can measure with the tools you have.

Why Grams and ML Are Not the Same

Grams measure weight, and milliliters measure volume. The link between them is density, which is how many grams fit in 1 ml. The gram was first defined using water, so 1 ml of water weighs very close to 1 gram. The USGS puts the exact figure a little lower, at 0.998 grams per ml at 70°F (21°C), which is too small to matter in a kitchen.

One Gram Is Not Always One ML

Only water and liquids close to it, like milk and cream, convert at about 1 to 1. Oil and sugar are lighter per ml, so the same grams take up more space. Honey and salt are heavier per ml, so the same grams take up less. Pick the right ingredient before you convert.

Grams to ML Chart by Ingredient

This chart lists how many grams fit in 1 ml of each ingredient, and how much space 100 grams takes up. The values come from the cup weights on the King Arthur Baking ingredient weight chart and USDA FoodData Central, divided by the 236.6 ml US cup. Dry ingredients assume the spoon and level method, with brown sugar packed.

150 Grams, 100 Grams and 40 Grams in ML

150 grams of water is 150 ml, 150 grams of milk is 145 ml, and 150 grams of flour is 296 ml. 100 grams of oil is 119 ml, almost 20 percent more space than the same weight of water. 40 grams of sugar is 48 ml, which is about 3 1/4 tablespoons.

How to Do a G to ML Conversion

A g to ml conversion needs one number: the grams per ml of your ingredient, from the chart above. Divide the grams by that number to get ml. To go the other way, multiply the ml by the same number.

Grams to ML Example

For 200 grams of vegetable oil, 200 ÷ 0.837 = 239 ml. For 200 grams of honey, 200 ÷ 1.42 = 141 ml. The same weight fills very different spaces.

ML to Grams Example

For 250 ml of milk, 250 × 1.031 = 258 grams. For 100 ml of honey, 100 × 1.42 = 142 grams. Use this when a recipe lists ml but you prefer to weigh.

From ML to Cups and Spoons

One US cup holds 236.6 ml, and one tablespoon holds about 15 ml (NIST). So 239 ml of oil is about 1 cup, and 30 ml is 2 tablespoons. The cups to ml converter and tbsp to ml converter cover these steps in detail.

Tips for Converting Grams and ML

These habits keep your conversions close to the real amount. They matter most for baking, where small errors add up. A kitchen scale is still the most accurate tool.

Treat water, milk and broth as about 1 to 1. For these liquids, grams and ml are close enough for cooking.
Never use 1 to 1 for dry foods. 100 grams of flour fills almost twice the space of 100 grams of water.
Use cups for dry ingredients. For flour, sugar or cocoa, the grams to cups converter gives a measure you can actually use.
Read liquids at eye level. Set a clear jug on the counter and bend down to check the ml line.
Do not convert medicine yourself. Follow the dose on the label and use the dosing tool that comes with it.
