2 Cups Granulated Sugar in Grams
2 cups of granulated sugar weighs 396 g (spooned and levelled, King Arthur Baking). That single number is the whole point of this page, but the reason it matters is that cups measure volume and recipes live or die by weight. Granulated Sugar is one of those ingredients where a cup can hide a surprisingly wide range of weights, so converting to grams takes the guesswork out. Every figure on this page is approximate and comes from the King Arthur Baking value for granulated sugar, so when a recipe really matters, verify with a kitchen scale.
Why weighing granulated sugar beats scooping it
Granulated Sugar is the kind of ingredient where the cup method quietly fails. A cup is a volume measure, and the weight of a volume depends on how tightly the ingredient is packed, how fine it is, and even how humid the kitchen is. Two people filling the same cup of granulated sugar can easily end up with weights several grams apart, and in a recipe that calls for 2 cups, that difference doubles. Grams remove the variable entirely: 396 g of granulated sugar is 396 g of granulated sugar in any kitchen, on any day, in any hands. That is why professional recipes are written in grams, and why converting your cup measurements is the single cheapest upgrade you can make to your cooking. You do not need expensive equipment — a basic digital scale that reads to the gram costs less than a bag of good flour and pays for itself the first time a cake comes out right.
Granulated Sugar cups to grams conversion table
| Cups | Grams | Tablespoons (approx.) |
|---|---|---|
| 1/4 cup | 49.5 g | 3.1 g |
| 1/3 cup | 66 g | 4.1 g |
| 1/2 cup | 99 g | 6.2 g |
| 2/3 cup | 132 g | 8.2 g |
| 3/4 cup | 148.5 g | 9.3 g |
| 1 cup | 198 g | 12.4 g |
| 1 1/2 cups | 297 g | 18.6 g |
| 2 cups | 396 g | 24.8 g |
| 3 cups | 594 g | 37.1 g |
| 4 cups | 792 g | 49.5 g |
The tablespoon column is a bonus for recipes that call for a spoonful or two: one tablespoon of granulated sugar weighs about 12.4 g. Remember that a cup is 16 tablespoons, so the numbers in the table are just the cup weight divided by 16, rounded sensibly. For small amounts a scale that reads to the gram is far more reliable than a spoon, because a heaped tablespoon can weigh half as much again as a level one.
How the weight was measured
Spooned and levelled means the ingredient was measured the way King Arthur Baking measures it: spooned into the measuring cup until heaped, then levelled with a straight edge. Never scoop the cup through the bag or jar, and never tap the cup down, because both pack the ingredient and add weight. The source for the 198 g per cup figure is King Arthur Baking, and the confidence in the value is high. King Arthur Baking publishes a standard ingredient weight chart that recipe developers use as a reference, and this page follows it exactly rather than averaging across sources, because an average of two different measuring methods is a number that matches nobody's cup.
There is a dispute worth knowing about. King Arthur lists 198 g per cup; USDA FoodData Central rounds granulated sugar to 200 g per cup. The 2 g difference is rounding, not a real disagreement. The practical advice is simple: use the value in the table above, measure the way the table describes, and your results will match the recipes this site is built around. If a recipe you are following was written with a different value, follow that recipe's value instead of ours, because consistency within one recipe matters more than which authoritative number you pick.
Worked examples
A buttercream that needs 2 cups of granulated sugar
Buttercream is a ratio recipe: the sugar carries the structure, and too much of it makes the frosting stiff and gritty. For 2 cups of granulated sugar, weigh 396 g. If the frosting feels too sweet, the answer is not to guess at a smaller cup — it is to weigh a precise smaller amount, for example 297 g for 1 1/2 cups, and taste from there. Weighing makes small adjustments repeatable.
A jam or preserve batch
Preserves depend on the sugar ratio for setting and for keeping quality, so guessing is risky. A recipe calling for 2 cups of granulated sugar needs 396 g weighed out before you start, because once the fruit is boiling you do not want to be measuring sugar. Weigh it into a bowl first, and the rest of the process runs smoothly.
Scaling a cake recipe for a crowd
A cake that serves eight and uses 1 cup of granulated sugar becomes a cake for sixteen with 2 cups, or 396 g. Scaling sugar by volume compounds the error, and sugar is the ingredient where a 10% error is most noticeable — too little and the cake is dry and pale, too much and it is cloying and sinks. Weigh it, and the doubled cake behaves exactly like the original.
Common mistakes with granulated sugar
The most common mistake is scooping the cup through the container instead of spooning and levelling. Scooping packs the ingredient and can add 10 to 20 percent extra weight — enough to ruin a bake. The second mistake is using a liquid measuring jug for a dry ingredient, or a dry cup for a liquid: the two are calibrated differently and the meniscus on a jug is hard to read at 2 cups. The third mistake is forgetting to tare the scale, so the weight of the bowl gets counted as ingredient. Put the bowl on the scale, press tare so the display reads zero, and then add the ingredient. Finally, do not trust a cup that has been sitting in a humid kitchen: granulated sugar absorbs moisture from the air, and a cup weighed on a damp day is heavier than the same cup on a dry day. The scale does not care about humidity — it tells you what is actually there.
Frequently asked questions
How many grams is 2 cups of granulated sugar?
2 cups of granulated sugar weighs approximately 396 g, measured spooned and levelled. The figure comes from the King Arthur Baking value of 198 g per cup. All weights on this page are approximate — verify with a kitchen scale when precision matters.
Can I use a cup instead of weighing granulated sugar?
Yes, but spoon and level rather than scooping: spoon granulated sugar into the cup until heaped, then sweep a knife across the top. Scooping packs the ingredient and can add 10 to 20 percent extra weight. For 2 cups, fill and level the cup twice. Weighing 396 g is more accurate and, once you are used to it, faster.
Is 396 g exact for 2 cups of granulated sugar?
No — it is approximate. The per-cup value of 198 g comes from King Arthur Baking, and real-world variation in brand, grind, moisture and packing means your cup may weigh a few grams more or less. For most cooking that is fine; for baking, weigh with a scale and treat the table as your planning guide.
How many cups is 396 g of granulated sugar?
396 g of granulated sugar is 2 cups — the conversion works in both directions, since 198 g equals one cup. If your recipe is written in grams and your tools are cups, divide the gram weight by 198 to get cups.
How do I measure granulated sugar without a scale?
Use the spoon-and-level method: spoon granulated sugar into a dry measuring cup until it is heaped above the rim, then level it with the back of a knife. Do not scoop the cup through the bag and do not tap it down. For 2 cups, repeat for a second cup. It is less accurate than weighing 396 g, but it is the best cup method available.
