Understanding why grams-to-cups conversion depends on the ingredient
Each ingredient has a unique density. Choose your ingredient first — flour, sugar, butter, and water all weigh differently per cup.
Type in the number of grams from your kitchen scale or recipe. Our calculator handles any amount from 1g to 1000g+.
See the cups instantly — both as a decimal (e.g., 0.83) and as a friendly fraction (e.g., ⅚ cup). Perfect for adapting recipes.
The conversion formula is simple: cups = grams ÷ grams per cup. The grams-per-cup value is unique to each ingredient because of density differences.
For example: 100 grams of all-purpose flour ÷ 120 g/cup = 0.833 cups. But 100 grams of water ÷ 240 g/cup = 0.417 cups — a very different result!
| Ingredient | Grams per Cup | 1 Cup in grams |
|---|---|---|
| All-Purpose Flour | 120g | 120g |
| Bread Flour | 127g | 127g |
| Cake Flour | 114g | 114g |
| Whole Wheat Flour | 120g | 120g |
| Almond Flour | 96g | 96g |
| Coconut Flour | 128g | 128g |
Weight never lies. A "cup" of packed brown sugar can weigh up to 50% more than a loosely filled cup.
Professional bakers always weigh ingredients for repeatable, perfect results every time.
Grams are universal. Convert to cups (US), cups (metric), or any volume unit with confidence.
Everything you need to know about converting grams to cups
To convert grams to cups, divide the weight in grams by the ingredient's grams-per-cup value. For example, 100 grams of all-purpose flour ÷ 120 grams/cup = 0.83 cups. Use our calculator above to do this instantly for any ingredient.
Each ingredient has a different density. A cup of feather-light powdered sugar weighs much less than a cup of dense honey. This is why the conversion factor (grams per cup) is unique for each ingredient — you cannot use a single universal conversion.
One cup of all-purpose flour weighs approximately 120 grams. Bread flour is slightly heavier at about 127g/cup, cake flour lighter at about 114g/cup, and whole wheat flour about 120g/cup.
One cup of granulated (white) sugar weighs approximately 200 grams. Brown sugar is slightly heavier at about 220g/cup (lightly packed), while powdered/icing sugar is lighter at about 120g/cup.
Measuring by grams (weight) is significantly more accurate than measuring by volume (cups). Cups can vary depending on how tightly an ingredient is packed. Professional bakers always measure by weight for consistent results.
One cup of butter weighs approximately 227 grams (2 sticks in the US). Half a cup of butter is about 113 grams, and a quarter cup is about 57 grams.
