Cups to grams, done right.
A cup of flour weighs 120 g. A cup of honey weighs 340 g. Pick the ingredient and get the real number.
One US cup of all-purpose flour weighs 120 g, a cup of granulated sugar 200 g, a cup of butter 227 g and a cup of honey 340 g. Volume is not weight: the same cup holds a very different mass depending on the ingredient, which is why cup-based bakes fail. Pick your ingredient below for the exact number.

Australian recipes usually mean a 250 ml cup (about 4 percent more), older UK recipes a 284 ml cup.
Volume measurements lie: the same cup holds very different weights depending on what is in it. This converter uses per-ingredient densities based on the US cup (240 ml), so your bakes come out the way the recipe author meant them.
Questions people ask
How many grams is 1 cup of flour?
One US cup of all-purpose flour is 120 g when spooned into the cup and leveled off. Scooping straight from the bag packs it and can push the same cup to 145 g, which is the single most common reason a bake comes out dry.
Is 1 cup always 240 ml?
In US recipes yes, 1 cup = 240 ml. Australian recipes use a 250 ml cup and older UK recipes a 284 ml imperial cup. This converter uses the US cup, so add about 4 percent for Australian bakes.
Why do cups and grams give different results?
A cup measures volume, grams measure weight. A cup of flour is 120 g while a cup of honey is 340 g, because density differs. Baking is chemistry, so weight is the only measurement that transfers between kitchens.
How many grams is a tablespoon of butter?
One tablespoon of butter is about 14 g, since a cup of butter is 227 g and there are 16 tablespoons in a cup. The chart above lists the tablespoon weight for every ingredient.
Good to know
The reference weights assume flour spooned into the cup and leveled off. Scooping straight from the bag packs the flour and can add 20 percent more than the recipe wants.
This tool uses the US cup (240 ml). Australian recipes often mean a 250 ml cup, and old UK recipes may mean 284 ml. If a bake comes from Australia, add about 4 percent.
