Grams to Cups Calculator — Cooking & Baking
Convert any recipe weight in grams to US cups for common baking and cooking ingredients. Because each ingredient has a different density, the gram-to-cup ratio varies — flour, sugar, butter and oats all give different results for the same gram weight.

How does this calculator work?
Cups = grams ÷ grams-per-cup for that ingredient. Common reference weights: all-purpose flour 125 g/cup, white sugar 200 g/cup, butter 227 g/cup, rolled oats 90 g/cup. The result also shows tablespoons and teaspoons. Figures are estimates — weigh ingredients for precision.
Formula
How this is calculated
Volume measurements like "1 cup" are convenient in the kitchen but imprecise: a cup of flour weighs very differently depending on how it is scooped and packed, whether it is sifted, the humidity and the brand. Weighing ingredients in grams (or ounces) removes this ambiguity, and the calculator converts back to cups when a recipe demands them.
The conversion is straightforward: divide the gram weight by the number of grams one US cup of that ingredient weighs. These reference weights (also called cup weights) are standardized values from sources such as the King Arthur Baking company and the USDA. For example, one cup of unsifted all-purpose flour is taken as 125 g, so 240 g ÷ 125 g/cup ≈ 1.92 cups.
Treat all results as edible estimates. Cup weights can vary by ±10–15 % between brands, sifting methods and measuring technique (spoon-and-level vs. scoop-and-level). For baking where precision matters, always weigh on a kitchen scale. The tablespoon and teaspoon equivalents use the exact ratios: 1 cup = 16 tablespoons = 48 teaspoons.
Frequently asked questions
About 125 g for unsifted all-purpose flour using the spoon-and-level method. Sifted cake flour is closer to 100 g and bread flour about 130 g. Always check which method a recipe assumes.
Granulated white sugar is about 200 g per cup. Packed brown sugar is approximately 220 g, while sifted powdered (icing) sugar is roughly 120 g per cup.
Cup measurements are inherently imprecise — the actual gram weight per cup varies with ingredient brand, moisture content, sifting and how tightly the cup is packed. Reference figures exist for standardization, but your actual result may differ by ±10–15 %. A kitchen scale gives exact measurements every time.
