Why cups to grams depends on the ingredient
A cup is a measure of volume and a gram is a measure of weight. Nothing converts one to the other without knowing what is in the cup, because ingredients have wildly different densities.
grams = cups × grams per cup for that ingredient
One cup of corn syrup weighs 312 g. One cup of cocoa powder weighs 84 g — nearly four times lighter, same cup. Any converter that offers a single "cups to grams" answer is quietly assuming water.
Grams in one US cup, by ingredient
73 ingredients. Figures from the King Arthur Baking ingredient weight chart, which is the chart most modern American recipes are written against, checked 17 September 2026. Where the chart publishes a smaller measure — a tablespoon of honey, a teaspoon of baking powder — the per-cup figure here is that measure scaled up.

The flour block is the one worth scanning. Across 28 varieties the range runs from Flour, barley at 85 g a cup to Flour, semolina at 163 g — a 92% spread. Substituting one flour for another cup-for-cup changes the weight of the recipe before it changes anything about the gluten, which is why flour swaps so often fail for reasons that have nothing to do with the flour.
Why two charts disagree about a cup of water
Look up a cup of water and you will find both 227 g and 236.6 g, and neither is a typo.
- 236.6 g is the physical answer. A US cup is 236.6 ml by definition, and water weighs almost exactly 1 g per ml.
- 227 g is the baker's answer. It comes from treating a cup as 8 ounces by weight: 8 × 28.35 = 226.8 g.
The two differ by about 4%, which is nothing in a soup and quite a lot in a loaf. Baking charts use the round 227 g because it keeps every liquid on the same eight-ounces-to-a-cup footing as the dry ingredients on the same page; a physics table uses 236.6 g because that is what a cup of water actually weighs. If you are following a recipe, use the chart the recipe came from and stay inside it — mixing the two is how a hydration percentage drifts.
Flour is the one that ruins recipes
A cup of all-purpose flour can weigh anywhere from about 120 g to over 150 g depending purely on how it got into the cup. Scooping the cup through the bag compacts the flour and can add a quarter more than the recipe intended — which is the single most common reason home baking comes out dry and dense.
The reference figure of 120 g assumes the spoon-and-level method: spoon flour loosely into the cup, then level the top with a straight edge. If you bake regularly, weighing flour is the cheapest improvement available — and it is the reason professional recipes are written in grams in the first place.
Fluid ounces are not ounces
English uses one word for two different things, and recipes suffer for it:
- Fluid ounces (fl oz) measure volume. There are 8 in a US cup, always, regardless of contents.
- Ounces (oz) measure weight. One is 28.35 g.
They coincide only for water, and then only under the baker's convention above. A cup of flour is 8 fl oz by volume but just 4.2 oz by weight, so treating the two as the same nearly doubles the flour.
Volume conversions
| Measure | In cups | In millilitres |
|---|---|---|
| 1 teaspoon | 1/48 | 4.93 ml |
| 1 tablespoon | 1/16 | 14.79 ml |
| 1 US cup | 1 | 236.6 ml |
| 1 US pint | 2 | 473 ml |
| 1 US quart | 4 | 946 ml |
| 1 half gallon | 8 | 1.89 L |
| 1 US gallon | 16 | 3.79 L |
| 1 decilitre | 0.42 | 100 ml |
US, metric, and imperial cups all differ
| Cup | Volume | Used in |
|---|---|---|
| US customary | 236.6 ml | United States — the default in most online recipes |
| US legal | 240 ml | US nutrition labelling |
| Metric | 250 ml | Australia, New Zealand, most of Europe |
| Imperial | 284 ml | Older UK and Commonwealth recipes |
An Australian cup holds 6% more than an American one, and an old imperial cup holds 20% more. For a cake, 20% extra liquid is the difference between a sponge and a pudding — so it is worth knowing where a recipe came from.
Dry pints and quarts are different again. A US dry pint is 551 ml against 473 ml for a liquid pint, which is why a "pint of blueberries" is not the same measure as a pint of milk.
One measure that is not a volume at all: a large egg is 50 g out of the shell, which is the figure recipes assume when they call for eggs by count.
For weights on their own, use the weight converter; for oven temperatures, the temperature converter handles Celsius, Fahrenheit, and gas marks' underlying values.
Cooking Measurement Converter — frequently asked questions
How many grams is a cup?
It depends entirely on the ingredient. A cup of flour is 125 g, granulated sugar is 200 g, butter is 227 g, and honey is 340 g. A cup measures volume, so there is no single answer.
How many grams of flour in a cup?
125 g using the spoon-and-level method. Scooping the cup straight through the bag compacts the flour and can add 25% more, which is the usual cause of dry, dense baking.
Are fluid ounces the same as ounces?
No. Fluid ounces measure volume — 8 in a US cup — while ounces measure weight, at 28.35 g each. They match only for water. A cup of flour is 8 fl oz but only 4.4 oz by weight.
Is a US cup the same as a metric cup?
No. A US cup is 236.6 ml, a metric cup used in Australia and Europe is 250 ml, and an older imperial cup is 284 ml. That last one holds 20% more, which will change a cake.
How many cups are in a pint, quart, or gallon?
2 cups in a US pint, 4 in a quart, 8 in a half gallon, and 16 in a gallon. Dry measures differ — a US dry pint is 551 ml against 473 ml for liquid.
