How to use it
- Choose the Ingredient from the list.
- Choose the Measure, such as a US cup or Su bardağı (200 ml), and enter the Amount.
- Read the Weight in grams, or type grams in Or enter a weight in grams to get the measure back.
- Use the table to see the grams for each measure of the same ingredient.
How the grams are worked out
The USDA FoodData Central database gives the weight of one cup of many foods. This tool divides that weight by the volume of the cup, 237 ml, to get the grams in one millilitre, then multiplies by the millilitres of the measure. Water weighs 237 g in a cup, so it is exactly 1 g per millilitre.
grams per ml = grams per US cup ÷ 237
grams = amount × millilitres of the measure × grams per ml- One US cup is 237 ml (NIST Handbook 44, Appendix C).
- A tablespoon is 15 ml and a teaspoon 5 ml (NIST, metric spoons, which the US table lists as exact).
- Turkish measures come from the millilitres in a university course and a university hospital diet guide.
Which Turkish measures are included, and which are not
Turkish household glasses are not standard. A university hospital's diet guide gives one su bardağı of milk as 200 ml, and a university pharmacy course gives su bardağı as 240 ml, so both are listed. Measure your own glass if the difference matters to you.
The çay bardağı (tea glass) and tatlı kaşığı (dessert spoon) are not listed: the sources found give no single millilitre value for them, and the pharmacy course gives a range of 8 to 10 ml for the dessert spoon. Weigh those amounts instead.
What this calculator does not cover
- Packed or sifted amounts: the USDA gives one figure for each cup, and brown sugar or flour can vary by 10 % or more by how it was packed.
- Ingredients not in the list, such as cheese, nuts or fresh fruit, and foods with a different density when chopped or grated.
- Liquid measures on a jug or a scale that your kitchen may use. Check the markings on your own tools.
Worked example: one su bardağı of sugar
Granulated sugar weighs 200 g in a US cup of 237 ml, so it is 200 ÷ 237 = 0.844 g per ml. One su bardağı of 200 ml therefore weighs 200 × 0.844 = 168.8 g, which rounds to 169 g.
The same cup of 240 ml weighs 202.5 g. For 250 g of flour, the answer is 2 US cups, since one cup weighs 125 g.
| Measure | Millilitres | Sugar, grams |
|---|---|---|
| US cup | 237 | 200 |
| Su bardağı (200 ml) | 200 | 169 |
| Su bardağı (240 ml) | 240 | 203 |
| Tablespoon | 15 | 13 |
Frequently asked questions
How many grams are in a cup of flour?
A US cup of all-purpose flour is 125 g in the USDA figures. Sifted or spooned flour can be lighter, so weigh it when a recipe depends on the amount.
How many grams is a su bardağı?
It depends on the glass and on the ingredient. The page gives su bardağı at 200 ml and at 240 ml, from two Turkish sources; one su bardağı of sugar is about 169 g or 203 g.
Why is the weight of brown sugar different from white sugar?
Brown sugar is denser when packed, so a packed US cup is 220 g while a cup of granulated sugar is 200 g. The USDA figure for brown sugar assumes it is packed.
Is a tablespoon of butter 15 grams?
No. A tablespoon of butter is about 14 g, because butter is slightly lighter than water per millilitre. The table on this page shows the exact figure for each measure.
Can I convert grams back to cups?
Yes. Type the weight in grams in the box Or enter a weight in grams, and the page gives the amount of the chosen measure that weighs it.
