Convert any cup measurement to grams by ingredient. Values use the spoon-and-level method.
1 cup of All-purpose flour = 125 grams
1 cup of All-purpose flour = 4.41 ounces
Weights are for all-purpose flour measured using the spoon-and-level method.
Conversions are provided for informational purposes. Weight conversions for ingredients are approximate and vary based on how ingredients are measured and their specific brand or variety. For precise baking, a kitchen scale is recommended.
Cups to Grams for Any Baking Ingredient
Converting cups to grams is the most common measurement problem in baking. US recipes measure by volume. European recipes measure by weight. And even within US recipes, cup measurements are less precise than gram weights because they depend on how you scoop.
This converter handles over 30 ingredients. Enter any cup amount, pick your ingredient from the list, and get the exact gram weight. Results show in grams and ounces so you can use either.
Why You Can't Use One Number for All Ingredients
A cup is a measure of volume. It holds the same amount of space no matter what is inside it. But different ingredients fill that space with different weights. Feathers and rocks take up the same space in a cup, but they weigh very different amounts.
The same is true in baking. One cup of all-purpose flour weighs 125 grams. One cup of granulated sugar weighs 200 grams. One cup of honey weighs 340 grams. One cup of cocoa powder weighs 85 grams. You cannot convert cups to grams without knowing the ingredient.
This is why a single conversion multiplier doesn't work. Every ingredient has its own weight per cup.

How to Measure Flour Correctly
Flour measurement is where most baking errors happen. Scooping the measuring cup directly into the flour bag compacts the flour. One compacted cup of all-purpose flour can weigh 150 to 155 grams instead of 125. That is 30 extra grams per cup. In a recipe that calls for 3 cups of flour, scooping instead of spooning adds up to 90 extra grams. The result is a dense, dry bake.
The correct method is called spoon and level. Use a spoon to scoop flour into the measuring cup until it is slightly overfull, then use a straight edge to level off the top. Do not tap or shake the cup. This is the method used to establish all the weights in this converter.
If you use a kitchen scale, you skip this entirely. Weigh to 125 grams and you always get the same amount no matter how you scoop.
Grams vs. Cups for Baking
Grams are more precise. A digital kitchen scale accurate to 1 gram costs as little as $10. Once you start baking by weight, you will not go back. There is nothing to level off. Nothing to pack too tight. No need to wash 6 measuring cups.
That said, volume measurements work well for everyday cooking. Soups, stews, sauces, and savory dishes are forgiving. A tablespoon more or less of an ingredient rarely matters. Baking is different. Baking is chemistry. Precision matters.
This site gives you both options. Use grams when precision counts. Use cups when it doesn't.
US Cups vs. Metric Cups
If a recipe comes from Australia, New Zealand, or Canada, it may use a 250ml metric cup rather than the US standard of 236.59ml. The difference is about 5.5 percent. For small amounts this is not meaningful. For larger recipes it adds up.
All conversions on this site use the US cup (236.59ml). If you are using a metric cup and following a US recipe, your measurements will be slightly high.

One cup of all-purpose flour weighs 125 grams when measured using the spoon-and-level method. To measure correctly, spoon flour into the measuring cup until it overflows, then use a straight edge to level off the top. Never scoop the measuring cup directly into the flour bag. Scooping packs the flour and can add 20 to 30 grams per cup, which changes the texture and density of baked goods.
How many grams is 1 cup of sugar?+
One cup of granulated white sugar weighs 200 grams. One cup of packed brown sugar weighs 220 grams because it is more densely packed. One cup of powdered or confectioners sugar weighs only 120 grams because it is much lighter and airier than granulated sugar. Raw cane sugar weighs 200 grams per cup, the same as granulated. Always specify the sugar type when converting cups to grams.
How many grams is 1 cup of butter?+
One cup of butter weighs 227 grams, which equals 2 full sticks of US butter or 8 ounces. One-half cup of butter is 113 grams or 1 stick. One-quarter cup of butter is 57 grams or half a stick. Butter from European brands may have slightly different moisture content, but the difference in weight is small enough to use the same gram conversions for home baking.
Why do different ingredients weigh different amounts per cup?+
Cups measure volume, not weight. Different ingredients have different densities, so the same volume can weigh very different amounts. One cup of honey weighs 340 grams because honey is very dense. One cup of rolled oats weighs only 90 grams because oats are light and airy. One cup of water weighs 237 grams. This is why professional bakers and most European and UK recipes specify ingredient weights in grams instead of volume in cups.
How many grams is 1 cup of oats?+
One cup of rolled oats weighs 90 grams. One cup of quick oats also weighs approximately 90 grams. Steel-cut oats are denser and weigh approximately 175 grams per cup. Oats are one of the lightest common baking ingredients by volume, which is why a full cup of oats weighs significantly less than a cup of flour at 125 grams or a cup of sugar at 200 grams.
How many grams is 1 cup of honey?+
One cup of honey weighs 340 grams. Honey is one of the densest common baking ingredients, which is why it weighs nearly 3 times more per cup than rolled oats. One tablespoon of honey weighs approximately 21 grams. One teaspoon of honey weighs approximately 7 grams. When substituting honey for sugar in a recipe, use 0.75 cups of honey for every 1 cup of sugar and reduce other liquids by 3 tablespoons.
What is the most accurate way to measure baking ingredients?+
The most accurate way to measure baking ingredients is by weight using a digital kitchen scale. Weight measurement removes all variability from how ingredients are scooped, packed, or leveled in a cup. A digital scale accurate to 1 gram costs as little as $10 and produces consistent results every time. If using cups, use the spoon-and-level method for dry ingredients and fill liquid measuring cups at eye level on a flat surface.
