Why two thirds of a cup is not a single weight
The reason 2/3 cup of flour and 2/3 cup of honey weigh nothing alike is density. Flour is light and full of air, so two thirds of a cup of it is only about 83 grams. Honey is one of the densest things in the kitchen, so the same two thirds of a cup weighs far more. To turn a volume like two thirds of a 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 two thirds of a 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 2/3 cup?
There is no single answer, because a cup measures volume and different ingredients have different densities. Two thirds of a cup of flour is about 83 grams, of sugar about 133 grams, of butter about 151 grams and of water about 160 grams. The full table above lists 2/3 cup in grams for 45 ingredients.
How many grams is 0.67 cups?
0.67 cups is the decimal way of writing 2/3 cup (2/3 cup is 0.667 cups, which rounds to 0.67), so the two are the same measure and the same page answers both. 0.67 cups is 160 ml, and in grams it is about 83 g of flour, 133 g of sugar, 151 g of butter and 160 g of water. Because a cup measures volume, the weight of 0.67 cups changes with the ingredient, so read the exact figure from the table above.
How many grams is 2/3 cup of flour?
Two thirds of a cup of all-purpose flour is about 83 grams when spooned and levelled. Scooping straight from the bag packs in extra flour, so weighing is the reliable way to hit 83 grams.
How many grams is 2/3 cup of sugar?
Two thirds of a cup of granulated white sugar is about 133 grams. Sugar is dense and does not compress much, so a levelled cup and a scooped cup come out close.
How many grams is 2/3 cup of butter?
Two thirds of a cup of butter is about 151 grams. A full US cup of butter is 227 grams, which is two sticks or half a pound, so 2/3 cup scales directly from that.
Is 2/3 cup the same in US and metric cups?
This page uses US cups, where one cup is 240 millilitres, so 2/3 cup is 160 millilitres. A metric cup is 250 millilitres, so the same fraction holds a little more. Converting to grams removes the difference entirely.
