Volume and weight are not interchangeable in the kitchen: a cup of flour weighs about 120–125 g, while a cup of granulated sugar is around 200 g. That is why recipes converted with a single “cup = 240 g” rule come out wrong. Accurate conversion needs the density of the actual ingredient.
This converter ships with 20+ ingredient densities, so pick flour, sugar, butter, honey, or cocoa and get a real answer. It also handles oven temperatures (°F ↔ °C ↔ Gas Mark), volume units, and fractional inputs like 1/2 or 3/4 cup — plus pan-size scaling when your tin does not match the recipe.
Convert cups to grams in 3 steps
- Open the faymox Cooking Converter.
- Pick your ingredient from the list of 20+, then enter the amount in cups — fractions like 1/2 work too.
- Read the grams instantly. Switch tabs for oven temperature or volume conversions when the recipe needs those instead.
FAQ
Why do different ingredients give different grams per cup?
Because a cup measures volume, not weight. Dense ingredients like honey pack more mass into the same cup than airy ones like flour — the converter uses each ingredient’s real density.
Can I convert oven temperatures too?
Yes — °F, °C, and Gas Mark convert both ways, which covers American, European, and British recipes.
Does it handle fractions like 2/3 cup?
Yes, type fractions directly (1/2, 1/3, 2/3, 3/4) and they are parsed exactly.
