Cups of Brown Sugar to Grams Converter
This page converts cups of packed brown sugar into grams, the way serious bakers weigh ingredients. One US cup of packed brown sugar is about 213 g, so the conversion is a multiplication by 213. Because packed brown 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 brown sugar to grams
Multiply the number of cups by 213. For example 4 cups of packed brown sugar is 4 × 213 = 852 g. To go the other way, divide grams by 213: 852 g ÷ 213 = 4 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. Brown sugar is measured firmly packed; packed, a cup weighs roughly 200 to 220 g, while loosely scooped it is much lighter. The figure of 213 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 brown sugar to grams FAQ
How many grams are in one cup of packed brown sugar?
One US cup of packed brown sugar weighs about 213 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 packed brown sugar and grams in my head?
Round the factor to about 210 g per cup: 4 cups is then about 840 g against an exact 852 g.
Why do recipes disagree about the weight of a cup of packed brown sugar?
Brands, sifting and scooping style change how much fits in the cup. Brown sugar is measured firmly packed; packed, a cup weighs roughly 200 to 220 g, while loosely scooped it is much lighter.
Should I weigh packed brown sugar instead of using cups?
Yes, if you can. Weight is repeatable, so a recipe that calls for 426 g of packed brown sugar will give the same result every time, while two cups can differ by 10 to 20% from one person to the next.
