How to use
Select an ingredient from the dropdown, enter the amount in grams or cups, and the converter instantly shows the equivalent measurement. Use the direction tabs or swap button to toggle between grams-to-cups and cups-to-grams. The reference table below shows all 20 ingredient densities at a glance.
Formula
Examples
Baking a cake
A recipe calls for 250g of all-purpose flour. At 125g per cup, that equals exactly 2 cups. For 150g of granulated sugar at 200g per cup, you need 3/4 cup.
Converting a European recipe
A French pastry recipe lists 340g of honey. Since honey weighs 340g per cup, that is exactly 1 cup. Heavier liquids like honey pack more weight into the same volume than lighter ingredients like flour.
Scaling recipes
To halve a recipe that calls for 2 cups of brown sugar, convert to grams first: 2 cups x 220g = 440g. Half is 220g, which is exactly 1 cup. Working in grams makes scaling more precise.
Frequently asked questions
Why do different ingredients have different grams per cup?
A cup is a unit of volume, not weight. Different ingredients have different densities. A cup of honey (340g) weighs nearly four times as much as a cup of cocoa powder (86g) because honey is much denser. This is why converting by volume requires knowing the specific ingredient.
How should I measure flour for accurate cup measurements?
Use the spoon-and-level method: fluff the flour, spoon it into the cup, and level off with a straight edge. Scooping directly from the bag packs the flour and can add 20-30% more weight. For best accuracy, use a kitchen scale and measure in grams.
Are these densities exact?
These densities are averages from USDA FoodData Central and standard baking references. Actual density can vary slightly by brand, humidity, altitude, and how the ingredient is packed. For professional baking where precision matters, always weigh ingredients on a digital scale.
What is the difference between a US cup and a metric cup?
A US cup is 236.6 mL and a metric cup (used in Australia) is 250 mL. This converter uses US cups, which are standard in American recipes. If your recipe uses metric cups, multiply the cup result by 0.946 to convert.
