- All-purpose flour15.6 g0.551 oz by weight
- Granulated sugar25 g0.882 oz by weight
- Butter28.4 g1 oz by weight
As a volume, 1/8 cup is 30 ml, 2 tablespoons or 6 teaspoons for any ingredient (US cup, 240 ml).
An eighth of a cup is a small measure used for concentrated ingredients like extracts, spices or a modest pour of oil, and it is exactly half of a quarter cup. Because it is one eighth of a full cup, an eighth cup of flour is about 16 grams and an eighth cup of sugar is about 25 grams, small enough that a kitchen scale gives a steadier result than a measuring cup.
Also written as 0.125 cup, an eighth of a cup.

Why an eighth of a cup is not a single weight
The reason 1/8 cup of flour and 1/8 cup of honey weigh nothing alike is density. Flour is light and full of air, so an eighth of a cup of it is only 15.6 grams. Honey is one of the densest things in the kitchen, so the same an eighth of a cup weighs 42.5 grams. To turn a volume like an eighth 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 an eighth 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 1/8 cup?
It depends on the ingredient, because a cup measures volume and every ingredient has its own density. In US cups of 240 ml, 1/8 cup is 15.6 grams of all-purpose flour, 25 grams of granulated sugar, 28.4 grams of butter and 30 grams of water. The table above lists 1/8 cup in grams for all 48 ingredients.
How many grams is 0.125 cup?
0.125 cup is the decimal way of writing 1/8 cup, so it weighs exactly the same: 15.6 grams of all-purpose flour, 25 grams of granulated sugar or 28.4 grams of butter. As a volume it is 30 ml in US cups.
How many grams of flour is 1/8 cup?
An eighth of a cup of all-purpose flour weighs 15.6 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 15.6 grams. Bread flour and cake flour weigh slightly differently; both are in the table above.
How many grams of sugar is 1/8 cup?
An eighth of a cup of granulated white sugar weighs 25 grams. Packed brown sugar is heavier at 27.5 grams and powdered sugar lighter at 15 grams, so check which sugar the recipe means.
How many grams of butter is 1/8 cup?
An eighth of a cup of butter weighs 28.4 grams, which is a quarter of a stick of US butter, or 2 tablespoons. A full US cup of butter is 227 grams, which is two sticks.
How many tablespoons is 1/8 cup?
1/8 cup is 2 tablespoons or 6 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 1/8 cup the same in US and metric cups?
Not quite. This page uses the US cup of 240 ml, so 1/8 cup is 30 ml. A metric cup is 250 ml, so 1/8 cup in metric cups is 31.3 ml and holds 16.3 grams of flour instead of 15.6. Weighing in grams removes the difference.
