Frequently Asked Questions
-
help_outline How do I convert grams to cups?To convert grams to cups, divide the weight in grams by the grams-per-cup value for your specific ingredient. For example, 100g of all-purpose flour ÷ 120 g/cup = 0.83 cups.
-
help_outline Why does the cup measurement differ between ingredients?Different ingredients have different densities. A cup of flour (≈120g) weighs far less than a cup of honey (≈340g), so grams-to-cups conversions are ingredient-specific.
-
help_outline Is a US cup the same as a UK or Australian cup?No. A US customary cup = 236.6 mL. An Australian/metric cup = 250 mL. A UK cup is rarely used but also 250 mL. Our converter uses the US cup standard.
-
help_outline How many grams in a cup of flour?One US cup of all-purpose flour weighs approximately 120–125 grams, depending on whether it is scooped or spooned. We use 120g/cup as the standard.
-
help_outline How many grams in a cup of sugar?One US cup of granulated white sugar weighs approximately 200 grams. Brown sugar (packed) is approximately 220 grams per cup.
-
help_outline How many grams in a cup of butter?One US cup of butter weighs approximately 227 grams (2 sticks in the US). In metric regions, 250g is often used as a cup.
-
help_outline Can I use this converter for liquids like milk or water?Yes! Water has a density very close to 1g/mL, so 240g of water ≈ 1 cup (240 mL). Milk is slightly denser at about 245g per cup. Select the ingredient from the dropdown for an accurate result.
-
help_outline What is the most accurate way to measure ingredients?Using a kitchen scale to weigh ingredients in grams is the most accurate method. Volumetric cup measurements can vary by 20–30% depending on how the ingredient is packed into the cup.
