- All-purpose flour41.7 g1.47 oz by weight
- Granulated sugar66.7 g2.35 oz by weight
- Butter75.7 g2.67 oz by weight
As a volume, 1/3 cup is 80 ml, 5.33 tablespoons or 16 teaspoons for any ingredient (US cup, 240 ml).
A third of a cup sits between a quarter and a half, and it turns up constantly in cakes and muffins where quantities do not divide neatly. It is the hardest common fraction to judge by eye, which is exactly why a gram figure helps: a third of a cup of flour is about 42 grams and a third of a cup of sugar about 67 grams.
Also written as one third of a cup, 0.33 cup.
1/3 cup (0.33 cup) in grams for all 48 ingredients
A cup measures volume, so a third of a cupweighs a different amount for each ingredient depending on how dense it is. The most used ingredients come first, then the rest from A to Z. Each name opens that ingredient's full cup to gram table at the 1/3 cup row.

Why a third of a cup is not a single weight
The reason 1/3 cup of flour and 1/3 cup of honey weigh nothing alike is density. Flour is light and full of air, so a third of a cup of it is only 41.7 grams. Honey is one of the densest things in the kitchen, so the same a third of a cup weighs 113 grams. To turn a volume like a third 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 a third 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. Cup sizes also differ by country; see cup sizes compared.

Frequently asked questions
How many grams is 1/3 cup?
It depends on the ingredient, because a cup measures volume and every ingredient has its own density. In US cups of 240 ml, 1/3 cup is 41.7 grams of all-purpose flour, 66.7 grams of granulated sugar, 75.7 grams of butter and 80 grams of water. The table above lists 1/3 cup in grams for all 48 ingredients.
How many grams is 0.33 cup?
0.33 cup is 1/3 cup rounded to two decimals (1/3 cup is 0.333 cups), so the weights are practically the same: 41.7 grams of all-purpose flour, 66.7 grams of granulated sugar or 75.7 grams of butter. As a volume it is 80 ml in US cups.
How many grams of flour is 1/3 cup?
A third of a cup of all-purpose flour weighs 41.7 grams when it is spooned into the cup and levelled off. Scooping straight from the bag packs the flour down and adds weight, so a scale is the surest way to hit 41.7 grams. Bread flour and cake flour weigh slightly differently; both are in the table above.
How many grams of sugar is 1/3 cup?
A third of a cup of granulated white sugar weighs 66.7 grams. Packed brown sugar is heavier at 73.3 grams and powdered sugar lighter at 40 grams, so check which sugar the recipe means.
How many grams of butter is 1/3 cup?
A third of a cup of butter weighs 75.7 grams, or 5.33 tablespoons. A full US cup of butter is 227 grams, which is two sticks.
How many tablespoons is 1/3 cup?
1/3 cup is 5.33 tablespoons or 16 teaspoons, because one US cup holds 16 tablespoons of 15 ml. That holds for every ingredient, since cups and tablespoons both measure volume; only the weight in grams changes.
Is 1/3 cup the same in US and metric cups?
Not quite. This page uses the US cup of 240 ml, so 1/3 cup is 80 ml. A metric cup is 250 ml, so 1/3 cup in metric cups is 83.3 ml and holds 43.4 grams of flour instead of 41.7. Weighing in grams removes the difference.
