390 Grams to Cups Converter
This converter starts with 390 grams and adjusts the cup estimate by ingredient. Because density changes from one item to the next, 390g may be close to 2 cups sugar, a little over 3 1/4 cups flour, or around 1.6 cups water.
The calculator uses each ingredient’s approximate grams-per-cup value to turn 390 grams into cups, tablespoons, and teaspoons. Since cups measure volume and grams measure weight, lighter ingredients like flour, oats, and cocoa powder take up more cup space than dense ingredients such as honey, molasses, or peanut butter.

Why 390 Grams Converts Differently for Each Ingredient
390 grams is fixed on a scale, but not in a cup. The same weight can look much larger or much smaller depending on whether you’re measuring something airy like flour or something dense like honey, molasses, or peanut butter.
For the best baking results, weighing 390 grams is still the most reliable method because scooping, packing, sifting, chopping, and melting all change the volume. Even so, the converter and chart above make it easy to get a practical cup-based estimate when you need one.
