300 grams to cups
300 grams is a full-recipe quantity that maps to distinct cup amounts ingredient by ingredient.
Three hundred grams is where you're committing to a proper bake, like the flour base of a layer cake. Weight stays constant but volume doesn't, so 300g of flour, sugar, or butter each occupy a different stretch of the measuring cup.

Three hundred grams is a generous, round amount common for flour in larger bakes like big batches of cookies, bundt cakes, or bread. Because it is a fixed weight, it occupies very different cup volumes depending on what you are measuring. Three hundred grams of all-purpose flour (about 120 g per cup) is about 2.5 cups, while the same 300 g of granulated sugar (about 200 g per cup) is only 1.5 cups, a full cup less for the identical mass. Featherweight cocoa powder (about 85 g per cup) balloons 300 g to roughly 3.5 cups, and dense butter (about 227 g per cup) shrinks to about 1.32 cups. From one and a half cups to three and a half for one weight, the spread is enormous. Whenever a recipe calls for 300 g, identify the ingredient first, because no single cup value covers them all.
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.
