A cup of flour and a cup of sugar do not weigh the same, so a simple cups to grams formula will not work for baking. This free converter uses the real weight of each ingredient. Pick flour, sugar, butter, honey, oats or any of 50+ ingredients, enter your amount (fractions like 1 1/2 work too), and get an instant weight in grams, ounces, kilograms and pounds. You can also convert grams back to cups, or paste a whole recipe into the recipe converter and get every ingredient in grams with a total. It works with US, metric and UK cups, and there is no signup.
How to Use (show after the tool):
- Choose a mode: Cups → Grams, Grams → Cups, or Recipe Converter.
- Search for your ingredient, such as “brown sugar” or “butter”, and select it.
- Enter the amount (for example 1, 1.5 or 1 1/2) and choose the unit: cup, tablespoon, teaspoon, fl oz, ml or litre.
- Pick your cup standard (US, metric or UK) if you are not using US cups.
- Read the weight in grams, ounces, kilograms and pounds, then check the quick chart for common cup fractions.
- For a full recipe, use the Recipe Converter, add each ingredient, and copy the finished gram list.

FAQs:
How many grams are in 1 cup of flour?
One US cup of all-purpose flour is about 120 grams when spooned and leveled. Bread flour is about 127 g and cake flour about 114 g.
How many grams are in 1 cup of sugar?
One US cup of granulated sugar is about 200 grams. Packed brown sugar is about 213 g and powdered sugar about 120 g.
Why do different ingredients have different gram weights per cup?
Cups measure volume, while grams measure weight. Ingredients differ in density, so a cup of honey weighs far more than a cup of flour.
Is a US cup the same as a metric or UK cup?
No. A US cup is about 237 ml, a metric cup is 250 ml, and a UK imperial cup is about 284 ml. Choose your cup standard in the tool for the right result.
Are the results exact?
They are very close averages. How you scoop, sift or pack an ingredient can change the weight by 5 to 10 percent, so a kitchen scale is best for precise baking.
