About the Cups to Grams Converter
The Cups to Grams Converter turns American volume measures into weights and back. Type an amount, such as 1, 0.5 or 3/4, pick the unit (cup, tbsp, tsp, ml or g) and the ingredient, and the page shows the same amount in grams, millilitres, cups, tablespoons and teaspoons at once. It is made for following a US recipe with a kitchen scale, or for turning a metric recipe into cups.
A cup measures volume, not weight, so a cup of flour and a cup of sugar weigh very different amounts. The converter uses a table of grams per US cup for fourteen common ingredients, shown in full on the page. They are typical published household values, rounded. How you fill the cup matters: flour scooped straight from the bag can weigh 15% more than flour spooned in and levelled. Weighing always beats measuring by volume.
How to use it
Steps
- Type the Amount. Fractions such as 3/4 and mixed numbers such as 1 1/2 work.
- Choose the Unit you have and the Ingredient.
- Read the amount in every other unit. To scale a whole ingredient list instead, switch to Scale a recipe or open the Recipe Scaler.
The conversions
The converter uses the US customary cup: 1 cup = 236.588 ml, 1 tbsp = 1/16 cup and 1 tsp = 1/48 cup. With an ingredient that weighs grams per cup, an amount of cups weighs
Grams and millilitres show whole numbers from 10 upwards and one decimal below 10. Cups and spoons round to kitchen fractions.

Frequently asked questions
How many grams are in a cup of flour?
About 125 grams for spooned and levelled all-purpose flour, from the table on this page. Scooping straight from the bag packs it down and can give 140 grams or more.
Why is a cup of sugar heavier than a cup of flour?
A cup is a volume, and ingredients weigh different amounts for the same volume. Granulated sugar is denser than flour, so a cup weighs about 200 grams against flour's 125.
Which cup does the converter use?
The US customary cup of 236.588 ml, with 16 tablespoons or 48 teaspoons to the cup. Metric cups of 250 ml and old imperial cups are not used.
Where do the grams per cup figures come from?
They are typical published household values, rounded, and the full table is on the page. How you fill the cup changes them, which is why weighing always beats measuring by volume.
Can I convert grams back to cups?
Yes. Choose g as the unit and type the weight. For example 250 grams of all-purpose flour is 2 cups, and 100 grams of granulated sugar is 1/2 cup or 8 tablespoons.
