Densities are approximate and based on the King Arthur Baking ingredient weight chart and USDA data. Real weight varies with how the ingredient is packed, sifted, or its moisture — for baking, a kitchen scale is most accurate.
Ingredient weight chart: cups to grams
A US cup is the same volume for every ingredient, but its weight in grams depends on how dense the ingredient is — a cup of flour is far lighter than a cup of honey. Use the chart below to convert common baking and cooking ingredients from cups, tablespoons and teaspoons to grams.

About this converter
This cooking converter answers the question recipes never quite agree on: how much does a cup of an ingredient actually weigh? The answer depends entirely on the ingredient. A cup of all-purpose flour is about 125 grams, a cup of granulated sugar is about 200 grams, a cup of butter is 227 grams, and a cup of water is roughly 237 grams — even though they all fill the same cup. That is because weight equals volume times density, and density differs for every ingredient. This tool stores realistic densities for dozens of common baking and cooking ingredients, then uses them to convert between volume (cups, tablespoons, teaspoons, millilitres, fluid ounces) and weight (grams, ounces, kilograms, pounds) in either direction. It supports US, metric and Japanese cups and spoons, so it works wherever your recipe comes from.
How to use
- 1 Choose your ingredient from the quick buttons or the full list.
- 2 Type the amount you want to convert.
- 3 Pick a unit — a volume unit like cups to get grams, or a weight unit to go the other way.
- 4 Read the result in grams, ounces, millilitres and cups, and copy any value.
How it works
Converting between cups and grams is not a fixed factor — it depends on density. The tool first converts your volume to millilitres (1 US cup = 236.6 mL, 1 metric cup = 250 mL, 1 Japanese cup = 200 mL), multiplies by the ingredient's density in grams per millilitre, and reports the weight. Going the other way, it divides the weight by the density to recover the volume. Density is why a cup of honey (about 340 g) weighs nearly three times as much as a cup of rolled oats (about 99 g). The densities here come from the King Arthur Baking ingredient weight chart and USDA data; they are reliable for everyday cooking but will shift a little depending on whether flour is scooped or spooned and how tightly brown sugar is packed.
Frequently asked questions
How many grams is 1 cup of flour?
One US cup of all-purpose flour weighs about 125 grams (4.4 ounces). Bread flour is a touch heavier at around 130 grams, while cake flour is lighter at about 113 grams. The exact figure depends on whether you scoop or spoon the flour, which is why weighing is more accurate than measuring by volume.
Why isn't a cup always the same weight?
A cup measures volume, not weight. Weight equals volume times density, and every ingredient has a different density. A cup of water weighs about 237 grams, but the same cup of flour holds only about 125 grams because flour is much less dense and full of air. That is why this converter asks which ingredient you are measuring.
Is a US cup the same as a metric or Japanese cup?
No. A US cup is 236.6 mL, a metric cup is 250 mL, and a Japanese cup is 200 mL. That means '1 cup' in an American recipe holds less than '1 cup' in a metric one. Use the unit selector to match the cup your recipe assumes.
Should I measure by weight or by volume for baking?
By weight, whenever you can. A kitchen scale removes the guesswork of how packed or sifted an ingredient is, giving consistent results — which matters most in baking. This tool is ideal for converting a recipe written in cups into grams so you can weigh instead.
