Grams to ml Converter

Q: How do I convert grams to ml?

Divide grams by the density in g/ml: ml = grams ÷ density . For water (density 1) it's a straight 1 g = 1 ml; for vegetable oil (0.92 g/ml), 100 g is 100 ÷ 0.92 ≈ 108.7 ml . Pick a preset above or type your own density.

Q: How do I convert ml back to grams?

Multiply: grams = ml × density . So 250 ml of milk (density 1.03) weighs 250 × 1.03 = 257.5 g . Switch the direction above to do it.

Q: How many ml is 100 g of flour?

About 181.8 ml (100 ÷ 0.55). Flour's density is only approximate — it varies with grind and packing — so for baking, weigh in grams rather than converting to volume.

Q: Can I use this for medicine?

No. Liquid medicines are measured by concentration (e.g. 250 mg per 5 ml), not density — using a generic grams-to-ml converter for medicine is dangerous. Always follow the label and your pharmacist or doctor's instructions.

Direction

Density (g/ml)Grams ≠ ml without density — a gram of flour takes up more room than a gram of water.

100 ml

100 g = 100 ml (at density 1 g/ml)

Formula: 100 g ÷ 1 g/ml = 100 ml

Cooking only: this converter is for food ingredients — water, milk, oil, flour and similar. Never use it for medicine; liquid medicines need the concentration on the label, not density.

How the grams to ml conversion works

The converter applies ml = grams ÷ density, with density in g/ml. Water's density is 1, so 100 g of water is exactly 100 ml. Lighter substances take up more room: 100 g of vegetable oil (density 0.92) is 100 ÷ 0.92 ≈ 108.7 ml. Going the other way, grams = ml × density.

Worked example: a recipe calling for 250 ml of milk (density 1.03) needs 250 × 1.03 = 257.5 g on the scale — noticeably more than water's 250 g, because milk is slightly denser.

Treat flour conversions as estimates: density varies with grind and how tightly it's packed, so the preset (0.55 g/ml) is only a typical value. When a bake has to be right, weigh with a scale instead of converting to volume.

grams to ml questions

How do I convert grams to ml?

Divide grams by the density in g/ml: ml = grams ÷ density. For water (density 1) it's a straight 1 g = 1 ml; for vegetable oil (0.92 g/ml), 100 g is 100 ÷ 0.92 ≈ 108.7 ml. Pick a preset above or type your own density.

Is 1 gram equal to 1 ml?

Only for water (and water-based liquids): 1 g of water is exactly 1 ml. For milk it's about 0.97 ml, for oil about 1.09 ml, and for flour roughly 1.82 ml — a gram of flour takes up nearly twice the room.

How do I convert ml back to grams?

Multiply: grams = ml × density. So 250 ml of milk (density 1.03) weighs 250 × 1.03 = 257.5 g. Switch the direction above to do it.
