Convert Grams to Cups by Ingredient
Because one cup of flour (120g) weighs almost half as much as one cup of sugar (200g) or butter (227g), true kitchen accuracy requires density-based conversion.

How We Calculate Conversions
Our conversion engine operates on empirical bulk density data, not arbitrary mathematical approximations.
Mass vs. Volume Physics
Grams measure mass (matter), whereas cups measure volume (space). Because ingredients possess different bulk densities, a single cup can hold 85g of cocoa powder or 340g of honey.
The Core Conversion Formula
We calculate volume from weight using the universal formula:
Cups = Weight (g) ÷ (Density in g/mL × Cup Volume in mL).
Authoritative References
Density benchmarks are verified against USDA FoodData Central and NIST Handbook 44 volumetric standards, calibrated for standard home baking conditions.
Frequently Asked Kitchen Conversion Questions
Why do baking recipes increasingly specify grams instead of cups?
Measuring dry ingredients by volume is notoriously imprecise. A single cup of flour can weigh anywhere from 110 grams (if sifted) to 160 grams (if scooped directly from the bag). A 45% variance can ruin delicate cakes, cookies, and breads. Grams measure mass directly on a kitchen scale, guaranteeing identical hydration and texture every single bake.
How many grams are in 1 standard US cup of all-purpose flour?
One standard US Legal cup of all-purpose flour weighs 120 grams when measured using the culinary "spoon-and-level" method. If you scoop directly with the measuring cup, the flour compacts, frequently weighing 140 to 150 grams per cup.
How many grams are in 1 cup of granulated white sugar?
One cup of granulated sugar weighs 200 grams. Because sugar crystals are dense and do not aerate like flour, sugar weight remains consistent whether scooped or poured.
Which cup measurement standard does GramsToCups.site use?
By default, we use the US Legal Cup (240 mL), which is the standard used for nutrition labeling and modern US kitchen tools. You can also select the US Customary Cup (236.6 mL), Metric Cup (250 mL used in the UK, Australia, and New Zealand), or UK Imperial Cup (284.1 mL) directly inside our converter.
How can I measure grams accurately if I do not own a kitchen scale?
Use our ingredient-specific conversion charts! For dry powders, fluff the ingredient with a fork, gently spoon it into your measuring cup without packing, and level the excess with the flat edge of a knife. For butter, rely on wrapper tablespoon marks (1 stick = 8 tbsp = 113.4g).
Why does packed brown sugar weigh more than white granulated sugar?
Brown sugar contains residual molasses film coating each crystal. Packing expels air pockets and allows the sticky molasses-coated grains to nest closely together, yielding a dense weight of approximately 220 grams per packed cup compared to 200 grams for granulated sugar.
