Example 1
- Direction: millilitres to grams
- Water
- 100 ml
100 g
How much does 100 ml of water weigh? 100 g, because density is 1.00 g/ml.
Ml to Grams
The calculator converts millilitres to grams with a product density. 100 ml of water is 100 g. 100 ml of oil is 91 g. 250 ml of sugar is 200 g, the same constant as on the cup page.
Cups, not millilitres, are on cup to mass. Spoons alone are on tablespoon and teaspoon.
Result
Enter millilitres or grams. The result will appear here.
How it works
The calculator multiplies millilitres by density in g/ml. For water, 100 ml is 100 g, because the density is 1.00 g/ml.
Oil is 0.91 g/ml, so 100 ml of oil is 91 g. Honey is 1.42 g/ml. Milk is 1.02 g/ml.
Sugar and flour use the same constants as the cup page: 200 g and 130 g per 250 ml, which is 0.80 and 0.52 g/ml.
The other way, you divide grams by density. 100 g of water is 100 ml.
A custom density is on the list. Enter a number greater than zero. These are kitchen constants, not a lab measurement.
This is not a cup and not a spoon. Cups are on the cup page. Spoon millilitres are on the tablespoon page.
Formula
g = ml × ρ; ml = g / ρ
ρ is in g/ml. Water 1.00. Oil 0.91. Sugar 0.80. Flour 0.52.
How to use
- Choose millilitres to grams and water.
- Enter 100. The result is 100 g.
- Pick oil and enter 100. The result is 91 g.
- Pick sugar and enter 250. The result is 200 g.
100 g from 100 ml of water
Mass is millilitres times density. Sugar and flour keep the constants from the cup page.
- 1,00
- Density of water in g/ml. 100 ml of water is 100 g.
- 0,91
- Oil density in the table. 100 ml of oil is 91 g.
- 0,80
- Sugar density: 200 g per 250 ml, as on the cup page.

Frequently asked questions
How much does 100 ml of water weigh?
100 g. The calculator multiplies millilitres by 1.00 g/ml.
How much does 100 ml of oil weigh?
91 g. Oil in the table is 0.91 g/ml. That is a kitchen constant, not a lab measurement.
How much does 250 ml of sugar weigh?
200 g. The same constant as on the cup page: 200 g per 250 ml.
How many millilitres is 100 g of water?
100 ml. Grams divided by 1.00 g/ml.
Is this the same page as cup to grams?
No. That page counts cups. Here you enter millilitres or grams and pick a product.
Where does 0.52 g/ml for flour come from?
130 g per 250 ml. The same table as on the cup page.
Can I enter my own density?
Yes. Pick a custom density and enter a number in g/ml greater than zero.
Can mass be negative?
No. Zero is allowed; after conversion the result is still zero.
Is this a lab weight?
No. These are kitchen constants. Loose flour and another brand of oil weigh differently.
Where do I convert a 15 ml tablespoon?
On the tablespoon and teaspoon page. That page is volume, without density.
Sources
Water density is taken as 1 g/ml. Sugar and flour keep the constants from the cup page.
