Converting Grams to Cups (and Back)
Cups and grams are not directly interchangeable because different ingredients have different densities. One cup of flour weighs about 125 grams, while one cup of sugar weighs about 200 grams.
For precise baking, weigh ingredients in grams with a kitchen scale. This converter helps when a recipe uses one system and you need the other.
Volumetric measurements (cups, tablespoons) depend on ingredient density — grams do not. One cup of all-purpose flour weighs approximately 120–130g using the spoon-and-level method, but 150–160g if scooped directly from the bag (packed). This 25% difference can significantly affect baking results. Weight measurements are unambiguous.
Common conversions: 1 cup flour (APF) ≈ 125g; 1 cup sugar (granulated) ≈ 200g; 1 cup brown sugar (packed) ≈ 220g; 1 cup butter ≈ 227g (2 sticks); 1 cup water/milk ≈ 240g; 1 cup cocoa powder ≈ 100g; 1 cup rolled oats ≈ 90g; 1 cup honey ≈ 340g.
The calculator applies average density values — actual ingredient density varies by brand, humidity, and packing method. For baking precision, measuring by weight (using a kitchen scale) is always more accurate than by volume. Highly accurate baking (macarons, soufflés, delicate pastry) should always use weight.
Liquid-solid distinction: the densities used here are for dry, uncompressed measurements at room temperature. Do not use solid-food density for liquid substitutes — liquids have their own densities (water 1 g/ml, honey 1.4 g/ml, oil 0.91 g/ml). The cup-to-gram converter uses stored density tables; if your specific ingredient isn't listed, use a kitchen scale for exact measurement.
