How many cups is 300 grams of sugar?

Converting between grams and cups for sugar or other ingredients is a common need when baking or cooking. Knowing the right conversions allows you to accurately measure out the amounts called for in recipes. In this article, we’ll provide a quick answer up front, then explain the full conversion step-by-step, provide additional examples, and summarize the key takeaways.

Quick Answer

300 grams of sugar is approximately 1 1/2 cups of sugar.

The Detailed Conversion

To convert grams of sugar to cups, we need to know the conversion ratio between the two units. For granulated white sugar, the conversion ratio is:

1 cup of granulated white sugar = 200 grams

So for 300 grams of sugar, we calculate:

  • 300 grams sugar x (1 cup / 200 grams) = 1.5 cups

Therefore, 300 grams of granulated white sugar equals 1 1/2 cups.

Checking Our Work

To double check, we can go backwards and convert 1 1/2 cups of sugar back to grams:

  • 1.5 cups sugar x (200 grams / 1 cup) = 300 grams

This confirms our calculation is correct.

More Examples

Using the same process, here are some additional examples converting between grams and cups of granulated sugar:

Grams Cups
100 grams 1/2 cup
200 grams 1 cup
400 grams 2 cups
800 grams 4 cups

This shows that for every 200 grams of granulated sugar, you have 1 cup. So doubling or halving the grams doubles or halves the cups.

Cups to Grams

You can also go from cups back to grams using the same ratio:

  • 2 cups sugar x (200 grams / 1 cup) = 400 grams

No matter which direction you are converting, grams to cups or cups to grams, the same 200 grams = 1 cup ratio holds true.

When Accuracy Matters

For the most accurate measurements in baking, it’s best to actually weigh ingredients with a kitchen scale instead of using cup conversions. This eliminates any variance in the density or air pockets within the sugar or other dry ingredients.

But for everyday cooking and most recipes, the gram-to-cup conversions provide enough accuracy. Just be sure you are using the proper 200 grams = 1 cup ratio specifically for granulated white sugar. The conversion will be different for brown sugar, confectioner’s sugar, or other sugar types.

Tips for Measuring Sugar

When measuring out sugar using cup measurements, here are some helpful tips:

  • Use dry measuring cups, not liquid measuring cups
  • Level off the top with a straight edge like the back of a butter knife
  • Break up any large clumps before measuring
  • Slightly overfill the cup, then level it off for maximum accuracy

Be sure to level, not pack, the sugar when measuring by cup. Packing sugar tightly increases its density and therefore the actual weight in grams.


Knowing how to convert between grams and cups for sugar, and having a few examples for reference, can make measuring for recipes much easier. The key takeaways are:

  • 300 grams of granulated sugar equals 1 1/2 cups
  • Use a 200 grams = 1 cup conversion ratio for granulated sugar
  • Measure accurately using dry measuring cups, leveling off the top
  • Weighing with a scale is the most precise method

Having the ability to move between grams and cups allows flexibility in working from recipes in metric or US customary units. So next time you need to know how many cups are in a certain number of grams of sugar, you’ll know just how to calculate the conversion.

Sugar is an important ingredient in many baked goods, candy, and desserts. It provides sweetness, structure, moisture retention, browning capabilities and food for yeast in baked goods. Granulated white sugar, sometimes called table sugar or cane sugar, is the most common type used in home kitchens. It comes from either sugarcane or sugar beets which are processed to extract the sugar.

Granulated sugar can range in crystal size from fine to coarse sand. Baker’s special sugar has the finest crystals, similar to superfine sugar. while varieties like sanding sugar have large, coarse crystals. The size of the crystals determines how quickly the sugar will dissolve when used. Finer sugar dissolves more rapidly.

When sugar crystals are heated, they melt into a syrup. As they cool, the syrup recrystallizes with smaller crystal size. This process is used to produce superfine sugars and fondant. Confectioner’s sugar is granulated sugar that has been ground to a fine powder with added cornstarch to prevent caking.

Brown sugar is white sugar combined with molasses for color and flavor. The amount of molasses determines whether it is light or dark brown sugar. Muscovado sugar is an unrefined brown sugar made from the juice of sugarcane with high molasses content. Turbinado and demerara sugars are also less refined with large golden crystals.

Sugar enhances browning in baked goods through the Maillard reaction. This occurs between the sugars and proteins at high temperatures, resulting in the characteristic brown crust and flavors. Sugars caramelize when heated to create sweetness, color, and complex flavors. Specific recipes rely on sugar reactions for desired outcomes.

When using sugar in baking, measuring accurately is important for achieving proper structure, sweetness, moisture, and texture in cookies, cakes, breads and pastries. Too much or too little sugar can result in baked goods that are dry, sticky, crumbly, hard, or chalky.

For sugar measurements in cups, leveling off the top surface is key for accuracy. Spooning sugar directly from the bag into a dry measuring cup means it will likely be compacted. For best results, fluff the sugar in the bag or container first with a fork or spoon. Then overfill the measuring cup and sweep off the excess.

Be careful when measuring sticky brown sugars or confectioner’s sugars which tend to compact and pack down into cups. Use a fork or sieve to break up any clumps. Confectioner’s sugar may need gentle sifting before measuring to remove lumps. Brown sugar benefits from having hard, packed areas broken up before measuring.

Kitchen scales provide the most accuracy since they eliminate the variability of scoop sizes, packing density, or other volume differences. Weight in grams is a more precise measurement than household cups. Any recipe will turn out best if the measurements are as accurate as possible.

When working from recipes with sugar amounts listed in grams, converting to cups using the 200 grams = 1 cup ratio allows you to measure out the sugar easily. This applies only to granulated white sugar. As discussed earlier, the conversion will be different for brown sugar due to the molasses content.

Being able to switch between gram and cup measurements gives flexibility in trying recipes from different countries. Recipes originating in Europe or Australia often list ingredients by weight in grams. U.S. recipes more commonly use volume measurements like cups or teaspoons.

Some bakers even choose to weigh out all their ingredients even when using U.S. recipes. While this requires a kitchen scale, it eliminates the need to clean and store multiple measuring cups. Weighing wet ingredients like milk, cream, or oil can also improve accuracy over liquid measuring cups.

When following a recipe, be sure all the measurements are done using the same system – all weights or all volumes. Avoid mixing the two, for example weighing the flour but measuring the sugar in cups. Consistently using grams OR cups helps ensure proper proportions between the ingredients.

Sugar adds many important qualities to baked goods. Having awareness around the different types of sugar, techniques for accurate measurement, and converting between grams and cups allows bakers to use sugar effectively. With some basic knowledge of sugar’s role and measurement, both new and experienced bakers can have success with all kinds of recipes.

Granulated sugar, also called table sugar or white sugar, is the most common sweetener used in baking. It is highly refined from sugarcane or sugar beets. The refinement process removes all traces of molasses, leaving just the sugar crystals behind. These crystals are pure sucrose with no traces of minerals, vitamins or proteins.

Table sugar has medium-sized crystals that flow freely. This makes it easy to incorporate into batters and doughs. The crystal size also determines sweetness perception – smaller crystals have more surface area exposed, allowing quicker dissolution on the tongue. Granulated sugar strikes a favorable balance of flowability and dissolution.

Being pure sucrose, granulated sugar has a clean sweetness that doesn’t overwhelm baked goods. Cakes, cookies and other desserts highlight the flavors of butter, eggs, vanilla and other ingredients rather than the sugar itself. This blank canvas quality makes it the default choice for the majority of baking recipes.

Granulated sugar also performs several roles in baking beyond just making things sweet. The incorporation of air into creamed sugar and butter creates structure in cookies and cakes. Sugar absorbs liquid in doughs and batters, controlling moisture retention in the finished product. Caramelization and Maillard reactions cause desirable browning.

When creaming butter and sugar, small pockets of air get trapped between the crystals. This aeration continues as other ingredients like eggs or additional flour are incorporated. The air pockets expand upon baking, leading to increased volume and desirable texture in cakes, cookies, and quick breads.

Sugar is hydrophilic, meaning it attracts and retains moisture. By competing with starches and proteins for available moisture, sugar affects a baked good’s softness, moisture retention, and shelf life. Using the appropriate amount of sugar for a particular recipe results in products that are neither too dry nor too soft.

At high temperatures, sugars participate in various browning and caramelization reactions. This results in both darkening of the food’s exterior through Maillard reactions and development of complex caramelized flavors. Sugar allows baked goods to brown properly for an appetizing look and taste.

Granulated sugar can be made from either sugarcane or sugar beets. Cane sugar is most prevalent, while a smaller amount comes from sugar beets. The refinement process is similar for both plants. After harvesting and extracting the sugar using pressing and liquid extraction, the raw sugar syrup undergoes purification.

The initial raw sugar is very dark due to the presence of molasses, minerals, proteins and other impurities. It is dissolved, clarified and filtered multiple times to remove impurities. Then the clean sugar syrup is concentrated through boiling until supersaturated. Upon cooling and seeding with sugar crystals, the supersaturated solution crystallizes into granulated sugar.

The sugar crystals are then dried and conditioned to ensure free flow. Anticlumping agents like cornstarch may be added at this point. The final granulated sugar contains at least 99.9% sucrose. While some trace minerals from the original plant matter may still be present, granulated sugar is considered highly purified and refined.

There are some differences between cane sugar and beet sugar. Beet sugar tends to have a slightly higher moisture content. The refinement process may also leave more traces of minerals like calcium, magnesium and iron in beet sugar. However, in general, cane and beet sugar are highly similar products.

Granulated sugar contains no fiber, fat, protein or nutrients beyond trace amounts. Its calories come purely from carbohydrates. One teaspoon of white sugar contains about 16 calories and 4 grams of carbohydrates.

Due to the high refinement, there are no vitamins, minerals or antioxidants present. The purpose of granulated sugar in cooking is to provide sweetness, texture, moisture control and browning capabilities. It should not be considered a source of beneficial nutrients.

However, as an easily digested simple carbohydrate, sugar can provide a quick source of energy. The “sugar high” felt after consuming sweets comes from blood glucose levels rising rapidly.

Of course, excess sugar consumption is linked to increased risks for obesity, diabetes, heart disease and other ailments. Moderation is advised, even when using sugar for baking. But granulated sugar can have an appropriate place in a balanced diet if consumed sensibly.

Granulated sugar must be stored properly to prevent clumping or moisture absorption. An airtight container is ideal. Since sugar is hygroscopic, it will absorb water from humid air, causing hard clumps.

If sugar becomes hardened, place it in a dry bowl and break up the chunks with a fork. Or sift clumpy sugar through a mesh sieve to separate and break up any clumps. Storing sugar in an airtight container helps prevent this issue.

To measure granulated sugar, use dry measuring cups, not liquid measuring cups. Scoop it from the bag or container with the appropriate sized cup. Then level off the top using a straightedge. Avoid packing or compressing the sugar into the cup. Allow any excess to overflow.

For accuracy, you should fluff up the sugar in the bag first before scooping to prevent compaction. Overfill the measuring cup, then sweep off any excess heaping sugar with a knife or other straight edge.

You can substitute granulated sugar in recipes calling for superfine sugar by pulsing regular sugar in a food processor to break up larger crystals. Or use a 1:1 substitution since the crystal size difference has minimal impact.

For powdered sugar, likewise a 1:1 substitution will work but may result in a less smooth texture. Or you can make your own by blending granulated sugar in a high powered blender or food processor for 30 seconds to a minute until powdered.

Granulated brown sugars like muscovado can also substitute 1:1 for white sugar, but expect more molasses flavor. Coarse sugars like turbinado or demerara add nice crunch but measure differently due to air pockets.

All in all, granulated sugar is a versatile ingredient used in many baking recipes. Understanding its production, properties and behaviors allows bakers to use it effectively. With some basic knowledge, both novice and experienced bakers can achieve sweet success.
