Like many baking supplies, sugar is often sold in bulk. Knowing how many cups of sugar you’re purchasing can help you plan out different recipes and can also help you better plan out storage.
One of the most common sugar bag sizes is 2 kilograms, and it’s easy to figure out how many cups are in a bag of this size.

How many cups of sugar are in 1 kilogram?
Before you figure out how many cups of sugar are in a 2-kilogram bag, it can be beneficial to know how many cups are in 1 kilogram.
Cups are part of the imperial measuring system, and they’re used to measure a particular volume. Kilograms, on the other hand, are part of the metric system.
They measure weight, so cups and kilograms do not always convert evenly into one another.
However, 1 kilogram usually contains almost exactly 5 cups of white, refined sugar, which makes conversions much simpler.
How many cups of sugar are in a 2-kilogram bag?
Now that we know that there are about 5 cups of sugar in every kilogram, we can easily find out how many cups of sugar are in a bag of any size. All we need to do is multiply 5 by the number of kilograms.
For a 2-kilogram bag, we’d multiply 5 by 2 to find that a bag of this size contains about 10 cups.

What types of sugar are available?
Refined white sugar is the most commonly available sugar type, and it is used in a range of recipes. It’s very popular for baking things like cakes, muffins, and cookies.
It can also be used to add a touch of sweetness to savory recipes, such as marinara sauce. Plain white sugar is also commonly used in making candies or caramel.
Brown sugar is also relatively common. Aside from a darker color, brown sugar has a higher moisture content and a slightly richer flavor. This is because brown sugar has molasses in it.

Powdered or confectioner’s sugar is also commonly used in baking. Powdered sugar is the same as regular refined sugar, but it has been blended until it’s very fine.
Powdered sugar is often used for dusting cakes or donuts. It can also be mixed with milk, butter, or cream cheese to make frosting or icing.
There are 10 cups of sugar in a 2 kg bag.

Does brown sugar weigh more than white sugar?
Brown sugar has molasses in it, and it’s also slightly denser and moister. These factors mean that brown sugar tends to weigh a bit more than white sugar.
One cup of brown sugar weighs about 7.5 ounces, while 1 cup of refined white sugar weighs ever so slightly more than 7 ounces.
White sugar is more commonly sold in bulk or large bags, such as a 2-kilogram bag, so you’ll want to use the 7-ounce weight to figure out how many cups are in a kilogram.

There are about 35.3 ounces in 1 kilogram, and if we divide by 7, we get a number that’s only a little over 5, telling us that there are, as stated above, 5 cups of white sugar in 1 kilogram.
If we divide 35.3 by 7.5, we get 4.7. This is close enough to 5 that you could round up to estimate that there are also about 5 cups of brown sugar in 1 kilogram.
However, it’s more accurate to say that there are 4.7 cups of brown sugar in 1 kilogram, which means there are about 9.4 cups of brown sugar in a 2-kilogram bag.
Brown sugar isn’t as frequently sold in bulk, however, so you’ll usually be able to use the 5-cup rule.
Because it is so fine and airy, powdered sugar weighs less than refined white sugar.
