Why weigh instead of measure in cups?
Cup measurements vary depending on how you fill them. Scooping flour directly from the bag can pack in 30–50g more than a levelled spoon-fill — enough to make a bread dough noticeably stiffer or a cake turn out dry. A digital kitchen scale and gram measurements remove that variable entirely, giving you consistent, repeatable results every time.
This converter uses standardised culinary weight references for 21 common baking ingredients. Because every ingredient has a different density — honey is nearly three times denser than rolled oats — the conversion from cups to grams is ingredient-specific.
Common questions
How many grams is 1 cup of flour?
1 cup of all-purpose flour weighs approximately 125g when spooned and levelled. Scooping directly from the bag can give 145–155g. Bread flour is slightly heavier at 127g per cup.
How many grams is half a cup of flour?
Half a cup of all-purpose flour weighs approximately 62–63g when spooned and levelled. Scooping directly from the bag can push this to 70–80g due to compaction — another reason a scale gives better results.
How many grams is 1 cup of sugar?
1 cup of granulated white sugar is 200g. Packed brown sugar comes in at 213g per cup. Powdered (icing) sugar is lighter — around 120g per cup due to its fine, airy texture.
How many grams is 2 cups of sugar?
2 cups of granulated white sugar weigh 400g. For packed brown sugar, 2 cups is approximately 426g. Powdered sugar is lighter — 2 cups weighs around 240g.
How many grams is 1 cup of butter?
1 cup of butter weighs 227g — equivalent to 2 standard US sticks, or about 8 ounces.
How many grams is a third of a cup of butter?
One third of a cup of butter weighs approximately 76g. Because butter is dense and solid at room temperature, even small measurement errors affect fat-to-flour ratios noticeably in pastry.
How many grams is 1 cup of oats?
1 cup of rolled oats weighs approximately 95g. Oats are light with large air pockets between flakes — thick-cut and thin-cut oats can vary by around 20g per cup, making weighing especially useful.
How many grams is 1 cup of honey?
1 cup of honey weighs approximately 340g, making it one of the heaviest ingredients by cup. Honey is very dense and sticky — a significant amount clings to measuring cups, so always weigh honey for accuracy.
How many grams is 1 cup of cocoa powder?
1 cup of cocoa powder weighs approximately 100g. Cocoa is very light and fluffy, making it one of the easiest ingredients to over-measure by volume. Too much cocoa makes baked goods dry and intensely bitter.
Do grams-per-cup values vary by ingredient?
Yes — always. A cup measures volume, not weight. Because each ingredient has a different density, the gram equivalent per cup is unique to that ingredient. Use the dropdown above to select your ingredient for an accurate conversion.
GramScale uses standardized culinary weight references. Values may vary slightly by brand or scooping method.
