100 grams to cups
100 grams is a popular baseline, yet its cup equivalent changes completely from flour to butter to syrup.
A clean, round 100 grams is a baker's favourite reference point. But it's a weight, not a volume, so it spreads across the cup very differently per ingredient: roughly three-quarters of a cup of flour versus under half a cup of dense honey.

One hundred grams is the metric baker's favorite round number, common for flour, sugar, chocolate, and nuts because it scales so cleanly. But a clean weight does not mean a clean cup figure, since each ingredient has its own density. One hundred grams of all-purpose flour (about 120 g per cup) is roughly 0.83 cup, while 100 g of granulated sugar (about 200 g per cup) is just half a cup, half the volume for the same weight. Featherlight cocoa powder (about 85 g per cup) expands 100 g to nearly 1.2 cups, the biggest scoop in the lineup. Dense butter (about 227 g per cup) shrinks to about 0.44 cup, a little under 7 tablespoons. So 100 g to cups has no single answer: light, fluffy ingredients fill more volume, heavy ones fill far less.
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.
