How it works
Each baking ingredient has a specific density that determines how much it weighs per cup. This calculator stores those densities and uses them to convert between cups, grams, ounces, tablespoons and butter sticks. The densities are derived from the USDA National Nutrient Database and verified against common baking references from King Arthur Baking, Betty Crocker and the Joy of Cooking.
For butter, the calculator also supports the US stick format. One standard US butter stick equals 113 g (4 oz) or ½ cup. If you buy butter in blocks (common in Europe and Australia), 250 g is roughly 2.2 sticks or 1.1 cups. The calculator handles all these conversions so you can adapt any recipe to the butter format available in your country.
How the conversion works
Each ingredient has a fixed grams-per-cup density. The calculator converts your input to grams first, then from grams to every other unit. The key densities are: butter 227 g/cup (113 g/stick), all-purpose flour 120 g/cup, granulated sugar 200 g/cup and packed brown sugar 220 g/cup.
Worked example
A recipe calls for 3 sticks of butter, but your butter is sold in 250 g blocks. How much do you need?
US recipe user abroad
American recipes often use sticks of butter and cups, which can be confusing when you are shopping in a country that sells butter in 250 g blocks and measures in grams.

Tips for best results
Flour should always be spooned and levelled
Scooping flour directly from the bag with your measuring cup can add 20–30% more flour than intended. Always spoon flour into the cup and level it off with a straight edge.
Butter wrappers have measurement marks
US butter sticks have tablespoon markings printed on the wrapper. One stick = 8 tbsp. If you need half a stick, simply cut at the 4 tbsp line. No need to guess.
Use grams for brown sugar accuracy
Brown sugar density varies hugely depending on how firmly it is packed. Weighing in grams eliminates this variable and gives you exactly the amount the recipe developer intended.

Frequently asked questions
How much does one stick of butter weigh?
In the United States, one stick of butter weighs 113 g (4 oz) and measures ½ cup (8 tablespoons). Two sticks equal 1 cup (227 g / 8 oz). This is the standard US butter packaging format. European butter is often sold in 250 g blocks, which is slightly more than two sticks.
How many cups of flour are in 500 grams?
Using the standard density of 120 g per cup for all-purpose flour, 500 g ÷ 120 g/cup = 4.17 cups. Bread flour at 130 g per cup would be 500 ÷ 130 = 3.85 cups. Always check which flour type your recipe uses for accurate conversion.
Is brown sugar measured the same as white sugar?
No. Brown sugar is typically measured packed (pressed firmly into the cup), which gives a higher density of about 220 g per cup compared to 200 g per cup for granulated white sugar. Your recipe should specify "packed brown sugar" if that is the intended measure.
Can I substitute butter for margarine by weight?
Yes — butter and margarine have similar densities and can be substituted 1:1 by weight (grams) in most baking recipes. The texture and flavour will differ slightly, but the structural result will be comparable.
Why do some recipes give both cups and grams?
Thoughtful recipe developers provide both volume and weight measurements so that users with kitchen scales can achieve more consistent results while users without scales can still follow the recipe. Weight measurements eliminate the variability of scooping and packing.
