How to use the Cups to Grams Converter
- Choose the direction: Cups → Grams, or Grams → Cups.
- Pick the ingredient. Type in the search box to narrow the list, for example "flour" or "sugar".
- Enter the amount, using decimals or fractions such as 2/3 or 1 1/2, and select cup, tbsp, tsp or ml.
- Switch to Metric cup if your recipe is from Australia, New Zealand or another country that uses 250 ml cups.
- Press Convert (it also updates as you type) and read the grams and ounces, or use the quick table below.
How to convert cups to grams
Converting a volume to a weight needs the ingredient's density. The formula is grams = cups × grams per cup, and in the other direction cups = grams ÷ grams per cup. For tablespoons and teaspoons, remember that 1 US cup = 16 tbsp = 48 tsp = 236.59 ml.
Example: a recipe asks for 1 ½ cups of all-purpose flour. All-purpose flour weighs about 125 g per cup, so 1.5 × 125 = 187.5 g. Going the other way, 300 g of granulated sugar is 300 ÷ 200 = 1 ½ cups. And 3 tablespoons of butter is 3 × 227 ÷ 16 ≈ 42.6 g.

Tips for measuring by volume
How you fill the cup matters as much as the conversion. For flour, stir it, spoon it into the cup and level it with a knife; scooping directly from the bag can add 20% more. Brown sugar is the opposite: recipes expect it firmly packed. Measure sticky ingredients like honey and peanut butter in a lightly oiled cup so they slide out completely. When a recipe gives both cups and grams, the grams are the more reliable number.
Frequently asked questions
How many grams are in 1 cup of flour?
One US cup of all-purpose flour, spooned into the cup and leveled, weighs about 125 grams (4.4 oz). Bread flour is a little heavier at about 130 g, and cake flour lighter at about 114 g. Scooping straight from the bag packs the flour and can add 20–30 g.
How many grams are in 1 cup of sugar?
One US cup of granulated sugar weighs about 200 grams. Packed brown sugar is about 220 g per cup and powdered (icing) sugar about 120 g.
Why is there no single cups to grams number?
A cup measures volume, while grams measure weight. Different ingredients have different densities, so a cup of honey weighs almost three times as much as a cup of cocoa powder. You always need to know the ingredient.
How many grams of butter are in a cup?
One US cup of butter weighs 227 grams, which is two US sticks of 113.5 g each. One tablespoon of butter is about 14 g.
What is the difference between a US cup and a metric cup?
A US customary cup is 236.59 ml, while a metric cup used in Australia, New Zealand, Canada and the UK is 250 ml, about 5.7% larger. Use the Metric cup option for recipes from those countries.
How accurate are these conversions?
They use standard baking reference weights and are accurate enough for everyday cooking. Real weights vary with how you fill the cup, the brand and humidity, so for precise baking a kitchen scale is best.
