Cups to Grams Conversion for Common Ingredients
Cup measurements are the most common cause of baking mistakes. A cup measures volume, not weight — and because every ingredient has a different density, 1 cup of flour weighs far less than 1 cup of sugar or honey. Converting cups to grams removes that guesswork entirely and gives you consistent results every time. Use the chart below for quick reference, or try our free ingredient converter for any amount.

How to use this chart: Find your ingredient in the left column and read the gram weight in the right column. These values are based on the standard spoon-and-level method for dry ingredients and level fills for liquids. Scooping directly from the bag can add up to 30% more flour than the recipe intends, so always spoon and level for the most accurate results.
Frequently Asked Questions
How many grams is 1 cup of flour?
One cup of all-purpose flour weighs approximately 125g using the spoon and level method. Bread flour is 120g, cake flour is 100g, and whole wheat flour is 130g per cup. Scooping directly from the bag can add up to 30% more flour than the recipe intends.
Is a cup the same weight for all ingredients?
No. A cup is a volume measurement, not a weight measurement. Because different ingredients have different densities, 1 cup of flour (125g) weighs far less than 1 cup of sugar (200g) or 1 cup of honey (340g). This is why professional bakers use grams for accuracy.
Why do recipes use grams instead of cups?
Grams are a weight measurement, so they are exact and consistent every time. Cups measure volume, which means the same cup can hold different amounts depending on how an ingredient is packed, scooped, or sifted. A cup of flour can vary by up to 30%, which is why switching to grams is the single best way to improve baking consistency.
