How to Convert Sugar Grams to Cups
Cups = Grams ÷ Grams per Cup
For granulated sugar, our reference is 200 grams per US cup.
100g ÷ 200g per cup = 0.50 cup
500g ÷ 200g per cup = 2.50 cups
For another sugar type, replace 200g with that sugar’s grams-per-cup value.

Granulated vs Brown vs Powdered Sugar
Not all sugar fills a measuring cup in the same way. Crystal size, moisture, and packing affect how much a cup weighs. That is why we keep separate reference values for common sugar types.
| Sugar Type | Grams per US Cup | Difference vs Granulated | Measurement Note |
|---|---|---|---|
| Granulated Sugar | 200g | Reference | Loose crystals |
| Brown Sugar, Packed | 213g | +13g | Measured packed |
| Powdered Sugar | 120g | -80g | Fine and light |
Why Brown Sugar Is Different
Brown sugar contains moisture and is commonly measured packed into the cup. Packing removes air gaps and allows more sugar to fit into the same volume.
Our database therefore uses 213g per US cup for packed brown sugar, compared with 200g per cup for granulated sugar.
Why Powdered Sugar Is Lighter
Powdered sugar is very finely ground and behaves differently from granulated sugar. It can trap more air in a measuring cup, so one cup weighs considerably less.
Our powdered sugar reference is 120g per US cup. For this reason, you should not use the granulated-sugar chart for powdered sugar.
How to Measure Sugar Accurately
Granulated Sugar
Pour or spoon granulated sugar into a dry measuring cup, then level the top. Unlike flour, granulated sugar usually settles relatively evenly.
Brown Sugar
If a recipe asks for packed brown sugar, press it firmly into the measuring cup so it holds the shape of the cup when turned out.
Powdered Sugar
Powdered sugar may form lumps. If the recipe asks for sifted powdered sugar, follow that instruction because sifting can change the way the sugar fills the cup.
US Cup vs Metric Cup for Sugar
The main chart on this page uses a US customary cup of 236.588 ml. Changing the cup standard in the converter changes the adjusted grams-per-cup value.
| Cup Standard | Volume | Typical Use |
|---|---|---|
| US Customary Cup | 236.588 ml | Default on Grams To Cup Hub |
| US Legal Cup | 240 ml | Food labeling |
| Metric Cup | 250 ml | Many metric recipes |
| Imperial Cup | 284.131 ml | Older Imperial references |

Why Published Sugar Weights Can Differ
Ingredient charts from different publishers can show slightly different sugar weights. Brand, crystal size, moisture, packing method, sifting, and rounding can all affect the final reference value.
