Our grams in ml converter converts grams to milliliters (and milliliters to grams) for any ingredient. Since grams (g) measure mass and milliliters (ml) measure volume, you need the density of the substance to convert between them. This tool has a built-in database of densities for 17 common food ingredients — from water and milk to flour and honey — so you get accurate liquid volume and solid volume results without looking anything up.

Use it for cooking measurements, baking ingredient ratios, pharmaceutical dosage calculation, or scientific lab protocols. Just pick your ingredient, enter grams, and get ml. It works both ways.

How many grams to ml

The answer depends on what you're measuring. Grams and milliliters are different units — one is mass, the other is volume. The conversion factor between them is the density of the substance, measured in g/ml.

Density comparison: 100 grams in ml

Water 1.00 g/ml

100 ml

Milk 1.03 g/ml

97 ml

Honey 1.42 g/ml

70 ml

Sugar 0.85 g/ml

118 ml

Flour 0.60 g/ml

167 ml

Oats 0.39 g/ml

256 ml

Notice the pattern: denser substances take less volume. 100 grams of honey fills just 70 ml, while 100 grams of oats fills 256 ml. The same mass, very different volumes. That's why you can't just swap grams and ml — you need to know the density.

How do I convert grams to ml?

Since grams (g) describe mass and milliliters (ml) describe volume, you can't convert them directly. The conversion depends on the density of the ingredient. Here are the two formulas:

Grams → Milliliters

Volume [ml] = Mass [g] ÷ Density [g/ml]

Example: 150 g flour ÷ 0.60 g/ml = 250 ml

Milliliters → Grams

Mass [g] = Density [g/ml] × Volume [ml]

Example: 1.42 g/ml × 70 ml honey = 100 g

🙋

Density [g/ml] = Density [kg/l] = 0.001 × Density [kg/m³]

The density tells you how much mass fits in a given volume. A substance with high density (like honey at 1.42 g/ml) packs more mass into less space. A substance with low density (like flour at 0.60 g/ml) is lighter per volume — so the same grams fill more milliliters.

Grams to ml conversion for water

For water, the grams to ml conversion is the simplest case. The density of water is almost exactly 1 g/ml at room temperature. This means the mass of water in grams is (almost) equal to its volume in milliliters.

1 g=1 ml

10 g=10 ml

100 g=100 ml

250 g=250 ml

500 g=500 ml

1000 g=1000 ml

Note the almost part: water density changes slightly with temperature. At 4°C, it's exactly 1.0000 g/ml. At 20°C, it's 0.9982 g/ml. At 100°C (boiling), it's 0.9584 g/ml. For cooking measurements and practical kitchen conversions, the difference is too small to matter. But if you need precision volume measurement for chemistry or pharmaceutical dosage calculation, use a converter that accounts for temperature.

How to use this gram to milliliter converter?

Our g to ml converter is straightforward:

Pick the ingredient

Open the drop-down menu and select the ingredient you want to convert. The converter works for milliliters to grams too — it goes both ways.

Density is automatic

Our g to ml converter knows the density of the food. No need to look it up. You can enter a custom density value if you want — just select "Input your own ingredient."

Enter grams, get ml

Type the mass of your ingredient in grams and the grams in ml converter calculates the volume. Or enter ml to get grams — it acts as an ml into g converter too.

Related gram to ml converters

Here's how the grams to ml conversion works for the most common cooking and baking ingredients. Each one has a different density, so 100 grams produces a different volume every time.

💧

Grams to ml water

Density: 1.00 g/ml

100 g = 100 ml

Water is the baseline. 1 gram of water equals exactly 1 ml. Kitchen scales and measuring cups agree here.

🌾

Grams to ml flour

Density: 0.60 g/ml

100 g = 167 ml

Flour is light. 100 grams fills about 167 ml. Sifted flour is even lighter — one of the trickiest baking ingredient ratios to get right without a converter.

🍚

Grams to ml rice

Density: 0.85 g/ml

100 g = 118 ml

Raw rice has a density close to sugar. 100 grams of rice fills about 118 ml.

🥛

Grams to ml milk

Density: 1.03 g/ml

100 g = 97 ml

Milk is slightly denser than water. 1 gram to 1 ml milk is close but not exact — 100 grams of milk fills 97 ml.

🧊

Grams to ml ice

Density: 0.92 g/ml

100 g = 109 ml

Ice is less dense than liquid water — that's why it floats. 100 grams of ice takes up about 109 ml of space.

🧂

Grams to ml salt

Density: 1.22 g/ml

100 g = 82 ml

Table salt is dense. 100 grams packs into just 82 ml. A little salt goes a long way.

🫗

Grams to ml liquid

Varies by liquid

Most: 100 g ≈ 90–110 ml

Most common liquids — water, milk, vinegar, juice — have densities close to 1 g/ml. The grams to ml liquid conversion stays near 1:1 for most beverages.

🥄

Grams to ml powder

Varies: 0.4–0.8 g/ml

100 g ≈ 125–250 ml

Powders — cacao, protein, baking powder — are light and airy. The grams to ml ratio varies widely. Bulk ingredient handling matters: loosely scooped powder takes more volume than settles.

🍦

Grams to ml cream

Density: ~1.01 g/ml

100 g = 99 ml

Heavy cream (38% fat) has density around 0.99 g/ml. Light cream (13% fat) sits at about 1.01 g/ml. Both are close to water.

🧈

Grams to ml butter

Density: 0.91 g/ml

100 g = 110 ml

Melted butter is less dense than water. 100 grams of butter fills about 110 ml. Solid butter is denser — but we measure melted.

🫒

Grams to ml oil

Density: 0.92 g/ml

100 g = 109 ml

Vegetable oil, olive oil, and cooking oil equivalents all sit around 0.92 g/ml. 100 grams of any cooking oil fills about 109 ml.

🍬

Grams to ml sugar

Density: 0.85 g/ml

100 g = 118 ml

Granulated sugar is lighter than water. 100 grams fills about 118 ml. Powdered sugar is even lighter — different density, different conversion.

Frequently Asked Questions

How do I convert 100 g of honey to millilitres?

100 g of honey is about 70 ml. The density of honey is 1.42 g/ml. Divide the mass by the density: 100 ÷ 1.42 = 70.42 ml. So 100 grams of honey fills roughly 70 millilitres of volume.

Can grams convert to mL?

Yes — but you need to know the density of the substance. Grams measure mass, milliliters measure volume. The formula is: Volume [ml] = Mass [g] ÷ Density [g/ml]. For water (density 1 g/ml), 1 gram = 1 ml. For other ingredients, the conversion factor changes based on density.

Is grams and mL the same weight?

Not exactly. Grams (g) measure mass and milliliters (ml) measure volume. They only have a 1:1 ratio for water, which has a density of 1 g/ml. For everything else — flour, sugar, oil, honey — the number of grams and ml will differ. 100 ml of flour weighs about 60 grams. 100 ml of honey weighs about 142 grams.

How many grams to mL of water?

For water: 1 gram = 1 ml. This is because the density of water is approximately 1 g/ml at room temperature. So 100 grams of water = 100 ml, 250 grams = 250 ml, and 1000 grams = 1000 ml (1 liter). This 1:1 ratio makes water the simplest substance for grams to ml conversion.
