Cups of Sugar to Grams Converter
This page converts cups of granulated sugar into grams, the way serious bakers weigh ingredients. One US cup of granulated sugar is about 200 g, so the conversion is a multiplication by 200. Because granulated sugar is measured by volume in many American recipes but by weight in most European and professional ones, a quick, reliable conversion saves failed bakes.
How to convert Cups of sugar to grams
Multiply the number of cups by 200. For example 2 cups of granulated sugar is 2 × 200 = 400 g. To go the other way, divide grams by 200: 400 g ÷ 200 = 2 cups.

How much does a cup really weigh?
Density is the reason there is no single answer: a cup is a measure of space, not weight, so its weight depends on the ingredient. Granulated white sugar is dense and fairly consistent, at about 198 to 200 g per cup. The figure of 200 g per cup used here is a common baking reference value; your own flour, humidity and scooping habit can move it a few percent either way.
Measure by spooning the ingredient lightly into the cup and leveling the top with a knife; never press it down unless the recipe says "packed". Scooping straight from the bag compacts dry ingredients and can add 20% or more. A digital kitchen scale removes the guesswork entirely, and it also means fewer dishes to wash.
Cups of sugar to grams FAQ
How many grams are in one cup of granulated sugar?
One US cup of granulated sugar weighs about 200 g. That is a typical reference value, not an exact constant, because the weight changes with how the ingredient is packed.
What is the quickest way to convert cups of granulated sugar and grams in my head?
Round the factor to about 200 g per cup: 2 cups is then about 400 g against an exact 400 g.
Why do recipes disagree about the weight of a cup of granulated sugar?
Brands, sifting and scooping style change how much fits in the cup. Granulated white sugar is dense and fairly consistent, at about 198 to 200 g per cup.
Should I weigh granulated sugar instead of using cups?
Yes, if you can. Weight is repeatable, so a recipe that calls for 400 g of granulated sugar will give the same result every time, while two cups can differ by 10 to 20% from one person to the next.
