A cup of flour and a cup of honey are both one cup, and they weigh 120 g and 340 g. That is why a single grams to cups number never works. Pick your ingredient below and the conversion uses that ingredient’s own weight.
In grams
120 g
Weights assume flour and cocoa are spooned into the cup and levelled, and brown sugar is packed. Scooping straight from the bag can add 20–25% more flour, which is the usual reason a cookie comes out dry.
Quick answer: 1 cup of all-purpose flour weighs about 120 g, 1 cup of granulated sugar about 200 g, and 1 cup of butter 227 g. Every ingredient has its own weight per cup, so pick the ingredient in the grams to cups converter above rather than using one number for everything.
Why Your Cup Is Not My Cup
Flour compresses. Push the cup into the bag and you pack in up to 150 g. Spoon it in loosely and level the top with a knife and you get about 120 g. Nothing in the recipe changes, but you have quietly added a quarter more flour, and that is the most common reason a cookie turns out dry or a cake bakes up tough.
Every weight here assumes the gentle version: flour and cocoa spooned and levelled, brown sugar pressed firmly into the cup. If you own a kitchen scale, use it and skip the argument entirely.

Questions Bakers Ask
Is an ounce of flour the same as a fluid ounce?
No, and the confusion ruins recipes. An ounce is weight, a fluid ounce is volume. One cup is 8 fluid ounces of space, but only about 4.2 ounces of flour by weight. This tool treats ounces as weight.
Do American and British cups differ?
Yes. A US cup is 240 ml and an Australian cup is 250 ml, so an Australian cup carries about 4 percent more. The figures here are US cups, which is what most recipe blogs use.
How many grams are in 1 cup of flour?
About 120 g for all-purpose flour spooned into the cup and leveled. Scooped straight from the bag, the same cup can hold up to 150 g, which is why weighing flour gives more reliable cookies and cakes.
How many cups is 100 grams of sugar?
100 g of granulated sugar is exactly 1/2 cup. For packed brown sugar, 100 g is slightly less than 1/2 cup, and for powdered sugar it is a little under 1 cup, about 7/8 cup.
How many grams of butter are in 1 cup?
1 cup of butter weighs 227 g, which is two US sticks. Half a cup, or one stick, is 113 g, and one tablespoon is about 14 g.
