Granulated Sugar Cups to Grams Converter

How many grams are in a cup of granulated sugar?

1 US cup of granulated sugar is about 198 g on this page. KitchenMathHub uses that value as the selected reference for the sugar cups to grams chart and calculator. It is designed for ordinary granulated white sugar.

½ cup of granulated sugar is about 99 g. A quarter cup is about 50 g after practical rounding, ¾ cup is about 149 g, 1½ cups is about 297 g, and 2 cups is about 396 g.

Sugar uses a different grams per cup value from flour. Granulated sugar crystals settle into a cup differently from flour particles. That is why 1 cup flour can be about 120 g while 1 cup granulated sugar can be about 198 g.

Granulated sugar cups to grams for baking recipes

Sugar weight affects sweetness, spread, browning, texture, and moisture in many baked foods. It does more than make a recipe taste sweet. In cookies, cakes, brownies, and quick breads, changing the sugar amount can also change how the finished food behaves.

Use the recipe's stated sugar type. This page is for granulated sugar. Packed brown sugar, powdered sugar, coarse sugar, and liquid sweeteners need their own references. Do not use 198 g per cup for every ingredient that tastes sweet.

When a recipe gives cups and you want to bake by weight, converting the sugar to grams can make scaling easier. Gram amounts multiply cleanly, and a scale avoids the need to fill several cups when you are making a larger batch.

Sugar cups to grams examples

Example: 1 cup sugar in grams

1 cup of granulated sugar is about 198 g. If you are converting a cake recipe that calls for 1 cup sugar, place the mixing bowl on the scale, tare it, and add about 198 g.

Example: 1½ cups sugar in grams

1½ cups of granulated sugar is about 297 g. This amount can be easier to weigh than measuring one cup plus another half cup, especially when you are already weighing flour and butter.

Example: 2 cups sugar in grams

2 cups of granulated sugar is about 396 g. If you double a recipe that originally uses 1 cup, the weight doubles in the same way.

How to measure granulated sugar consistently

Fill the cup and level the top for a simple volume measurement. Granulated sugar generally settles more consistently than flour, but a heaped cup still holds more than a level cup.

Do not pack granulated sugar unless the recipe specifically tells you to. Packing is more commonly associated with brown sugar. Pressing granulated sugar into a cup can change the amount and makes comparison with a normal level cup less useful.

A kitchen scale gives the clearest result when the recipe provides grams. If a recipe says 198 g sugar, keep that weight instead of converting it to a cup and then measuring the cup again. The calculator is most useful when you are translating between measurement systems.

Granulated sugar, caster sugar, and other sugar types

Not every sugar should automatically use the granulated sugar reference. Crystal size affects how a dry ingredient fills a cup. Powdered sugar contains much smaller particles, while brown sugar is commonly measured packed and holds moisture.

The ingredient database treats important states separately. The Brown Sugar Cups to Grams page uses a packed brown sugar reference, while the powdered sugar page uses its own reference. This avoids pretending that every cup of sugar has the same mass.

If a recipe uses a regional sugar name, check what product it means before converting. Some names can overlap across countries, but the actual crystal size or product can still differ. The safest approach is to match the ingredient named by the recipe as closely as possible.

Convert sugar when scaling a cake or cookie recipe

Scale sugar with the same recipe factor as the other normal ingredient quantities. If a recipe uses 1 cup granulated sugar for 8 servings and you scale it to 12 servings, the factor is 1.5. The sugar becomes 1½ cups, or about 297 g with the reference used here.

Large recipe changes still deserve practical review. The arithmetic can scale sugar exactly, but baking behavior can change when a batter or dough becomes much larger, when the pan changes, or when several batches are combined.

Use the Recipe Scaling Calculator when you need to adjust the full ingredient list. Use the Cake Pan Conversion Calculator when the quantity change is driven by a larger or smaller cake pan rather than serving count alone.

Convert sugar grams to cups

198 g granulated sugar is about 1 cup. About 99 g is ½ cup, and 396 g is about 2 cups with the current reference. The reverse formula divides the gram weight by 198 g per cup.

Do not reuse the sugar formula for flour. For example, 198 g flour is not 1 cup under the flour reference. Ingredient identity must stay attached to the quantity when you convert a metric recipe to US cups.

The Grams to Cups Calculator lets you select granulated sugar and returns a practical cup value. It can also handle other supported ingredients with their own references.

Why sugar conversion charts can show different numbers

Different recipe sources can publish different cup weights. The exact number can depend on the sugar product, cup standard, measuring method, and house style used by the recipe developer.

Use the recipe author's own gram value when it is available. That is often the best way to reproduce a specific recipe. KitchenMathHub provides a declared general reference when the original recipe does not give a weight.

The important point is to avoid mixing values without knowing why. KitchenMathHub keeps the reference visible so you can understand where the number came from and decide whether it matches the recipe you are using.
