1 cup in Grams
One cup is the reference measure that every other amount scales from, and the amount people most often want in grams. The catch is that there is no single answer: one cup of flour is about 125 grams, one cup of sugar about 200 grams, one cup of butter 227 grams and one cup of honey around 340 grams.
Quick answer: one cup is 240 ml. In grams it is about 125 g of flour, 200 g of sugar, 227 g of butter and 240 g of water. Milk is close to 244 g.
1 cup in grams for every ingredient
A cup is a measure of volume, so one cup weighs a different amount for each ingredient depending on how dense it is. The table lists 1 cup in grams and ounces for 45 common baking ingredients. Tap any ingredient for its full cup to gram table and a guide to measuring it well.

Why one cup is not a single weight
The reason 1 cup of flour and 1 cup of honey weigh nothing alike is density. Flour is light and full of air, so one cup of it is only about 125 grams. Honey is one of the densest things in the kitchen, so the same one cup weighs far more. To turn a volume like one cupinto grams you multiply by the ingredient's density in grams per cup, which is exactly what the table above does for you.
For everyday cooking, measuring one cup with a measuring cup is perfectly fine. For baking, where the ratio of flour to sugar to fat decides whether a cake is tender or dense, weighing to the gram is far more reliable. A simple digital scale plus the figures here takes the guesswork out of it. Need a different amount? Try the cups to grams converter, or pick another common measure below.
Frequently asked questions
How many grams is 1 cup?
There is no single answer, because a cup measures volume and different ingredients have different densities. One cup of flour is about 125 grams, of sugar about 200 grams, of butter about 227 grams and of water about 240 grams. The full table above lists 1 cup in grams for 45 ingredients.
How many grams is 1 cup of flour?
One cup of all-purpose flour is about 125 grams when spooned and levelled. Scooping straight from the bag packs in extra flour, so weighing is the reliable way to hit 125 grams.
How many grams is 1 cup of sugar?
One cup of granulated white sugar is about 200 grams. Sugar is dense and does not compress much, so a levelled cup and a scooped cup come out close.
How many grams is 1 cup of butter?
One cup of butter is about 227 grams. A full US cup of butter is 227 grams, which is two sticks or half a pound, so 1 cup scales directly from that.
Is 1 cup the same in US and metric cups?
This page uses US cups, where one cup is 240 millilitres, so 1 cup is 240 millilitres. A metric cup is 250 millilitres, so the same fraction holds a little more. Converting to grams removes the difference entirely.
