About the Grams to Cups Calculator
Recipes from Europe, the UK and professional kitchens give ingredients in grams. If your kitchen has measuring cups but no scale, those recipes can look impossible to follow. The conversion depends on the ingredient: 300 grams of sugar fills about one and a half cups, but 300 grams of flour fills about two and a half.
This grams to cups calculator converts a weight into US cups for flours, sugars, butter, oil, liquids, cocoa, oats, rice and more. It gives the result as a decimal number of cups, as a combination of cups, tablespoons and teaspoons you can actually measure, and in metric cups and millilitres for Australian and Canadian measuring sets.

How Grams Are Converted to Cups
cups = grams ÷ weight of one cup of the ingredient
millilitres = cups × 236.6
metric cups = millilitres ÷ 250
The measuring breakdown rounds to the nearest eighth of a teaspoon and uses the standard relationships: 16 tablespoons to a cup and 3 teaspoons to a tablespoon.
Step-by-Step Example
300 grams of granulated sugar.
One cup of sugar: about 200 g
Cups: 300 ÷ 200 = 1.5 cups
To measure: 1 cup + 8 tbsp
Metric: 355 ml = 1.42 metric cups
100 grams of all-purpose flour.
Handy Fractions of a Cup
| Fraction | Tablespoons | Teaspoons |
|---|
| ¼ cup | 4 | 12 |
| ½ cup | 8 | 24 |
| ¾ cup | 12 | 36 | | 1 cup | 16 | 48 |
Knowing these makes it easy to build any amount from a basic set of measuring cups and spoons.
Converting Common Metric Amounts
Some weights come up again and again in recipes. For all-purpose flour, 100 grams is about four fifths of a cup, 250 grams about two cups and 500 grams about four cups. For granulated sugar, 100 grams is half a cup and 200 grams one cup. For butter, 100 grams is just under half a cup, or about 7 tablespoons, and a 250 gram block is a little over a cup.
When to Convert, and When Not To
Converting grams to cups works well for cooking — soups, stews, sauces, roasting vegetables — where a little more or less makes little difference. For baking, where the balance between flour, sugar, fat and liquid decides whether a cake rises or a dough holds together, converting to cups adds error. Two people measuring the same number of cups of flour can easily end up with weights 15% apart.
If you bake regularly from metric recipes, a digital kitchen scale is one of the cheapest and most useful tools you can buy. Until then, spoon dry ingredients into the cup and level them with a straight edge to get as close as possible to the weights used here.
Liquids Are Easier
For water and milk, grams and millilitres are almost the same: a gram of water is a millilitre, and milk is only slightly heavier. So 250 grams of milk is close to 245 ml, just over a US cup. Honey and syrups are much denser: 340 grams of honey is only one cup.
Converting Butter, Honey and Other Dense Ingredients
Dense ingredients convert very differently from flour. A 250 gram block of butter is only a little over one cup, while 250 grams of flour is two cups. Honey is denser still: 340 grams fills just one cup. Always choose the matching ingredient before converting, and for butter, remember that US sticks are marked in tablespoons on the wrapper, which is easier than packing a cup.
Metric Recipes and Oven Temperatures
Recipes written in grams usually give oven temperatures in Celsius, and sometimes for fan ovens. When converting a metric recipe for an American kitchen, remember to convert the temperature too: 180 °C is about 350 °F, and a fan oven usually needs about 20 °C less than a conventional one. Pan sizes are often given in centimetres as well, so check that your tin is close to the size the recipe expects.
Rounding Converted Amounts
Converted amounts rarely come out as neat fractions. For cooking, rounding to the nearest quarter or third of a cup is fine. For baking, keep a little more precision by using the tablespoon and teaspoon breakdown, which rounds to the nearest eighth of a teaspoon.
Keeping a Conversion Note
If you often bake the same metric recipes with cups, write the converted amounts on the recipe itself. After the first bake, adjust them if the result was too dry or too wet, and keep those tested figures for next time.

Common Mistakes
Assuming 100 grams is always the same number of cups.

Using US cups for an Australian recipe, or the reverse.
Converting baking recipes when a scale would be more accurate.
Rounding too early when several ingredients are converted.
