400 grams to cups
400 grams is a large amount whose cup equivalent varies widely between light and dense ingredients.
Four hundred grams signals a generous bake, think a double batch of muffins or a big bread dough. There's no single cup answer: airy flour fills several cups while the same 400g of dense butter or honey takes up far less room.

Four hundred grams is a large, round quantity typical of high-volume baking, like a double batch of cake flour or the sugar load in a big batch of jam or candy. At this scale, the difference between ingredients becomes especially striking because density compounds with quantity. Four hundred grams of all-purpose flour (about 120 g per cup) is about 3.33 cups, but the same 400 g of granulated sugar (about 200 g per cup) is only 2 cups, a difference of more than a cup for identical weight. Airy cocoa powder (about 85 g per cup) expands 400 g to nearly 4.7 cups, while dense honey (about 340 g per cup) collapses to roughly 1.18 cups. That is a swing of well over three cups for one fixed weight. At 400 g, eyeballing a cup conversion is risky, so weigh each ingredient separately.
Cups measure volume and grams measure weight, so there is no single grams-to-cups number, always pick the ingredient. Choose it in the calculator above to switch cup sizes too.
