1 2/3 cups (1.67 cups) is about 208 g of flour, 333 g of sugar and 378 g of butter. One and two thirds cups is a less common but real baking measure, equal to one cup plus two thirds of a cup, and it is easy to misjudge by eye. One and two thirds cups of flour is about 208 grams and one and two thirds cups of sugar is about 333 grams, so weighing takes the guesswork out.
Quick answer: one and two thirds cups, written 1.67 cups in decimal form, is 400 ml. In grams it is about 208 g of flour, 333 g of sugar, 378 g of butter and 400 g of water. Milk is close to 407 g.

Why one and two thirds cups is not a single weight
The reason 1 2/3 cups of flour and 1 2/3 cups of honey weigh nothing alike is density. Flour is light and full of air, so one and two thirds cups of it is only about 208 grams. Honey is one of the densest things in the kitchen, so the same one and two thirds cups weighs far more. To turn a volume like one and two thirds cupsinto 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 and two thirds cups 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 2/3 cups?
There is no single answer, because a cup measures volume and different ingredients have different densities. One and two thirds cups of flour is about 208 grams, of sugar about 333 grams, of butter about 378 grams and of water about 400 grams. The full table above lists 1 2/3 cups in grams for 45 ingredients.
How many grams is 1.67 cups?
1.67 cups is the decimal way of writing 1 2/3 cups (1 2/3 cups is 1.667 cups, which rounds to 1.67), so the two are the same measure and the same page answers both. 1.67 cups is 400 ml, and in grams it is about 208 g of flour, 333 g of sugar, 378 g of butter and 400 g of water. Because a cup measures volume, the weight of 1.67 cups changes with the ingredient, so read the exact figure from the table above.
How many grams is 1 2/3 cups of flour?
One and two thirds cups of all-purpose flour is about 208 grams when spooned and levelled. Scooping straight from the bag packs in extra flour, so weighing is the reliable way to hit 208 grams.
How many grams is 1 2/3 cups of sugar?
One and two thirds cups of granulated white sugar is about 333 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 2/3 cups of butter?
One and two thirds cups of butter is about 378 grams. A full US cup of butter is 227 grams, which is two sticks or half a pound, so 1 2/3 cups scales directly from that.
Is 1 2/3 cups the same in US and metric cups?
This page uses US cups, where one cup is 240 millilitres, so 1 2/3 cups is 400 millilitres. A metric cup is 250 millilitres, so the same fraction holds a little more. Converting to grams removes the difference entirely.
