Grams to Cups Sugar Converter
Convert grams to cups for granulated sugar — 200g = 1 cup, 80g = ⅖ cup, 100g = ½ cup. Ingredient-specific baking reference for recipe prep.
Granulated sugar
This page is ingredient-specific. It uses 1 cup granulated sugar ≈ 200 g and 1 tsp sugar ≈ 4.2 g and should be treated as an approximate kitchen reference.

About converting grams to cups for sugar
Why sugar needs its own grams to cups reference
Granulated sugar is much denser than flour or other baking ingredients, so a cup of sugar weighs significantly more than a cup of flour. That is why this page is specific to granulated sugar rather than offering a generic grams to cups table. Using the wrong conversion for the wrong ingredient leads to noticeably different results in baking.
Kitchen formula and assumption
This converter uses a practical baking reference of 1 US cup of granulated sugar being about 200 grams. That means 80 grams is about 0.4 cups, 100 grams is about 0.5 cups, 125 grams is about 0.625 cups, and 160 grams is about 0.8 cups. These are the values that come up most often in cakes, cookies, syrups, and dessert recipes.
When this page is useful
Use this page when a metric recipe lists sugar in grams but you need cup-based measurements, or when a US cup recipe needs to be scaled and weighed. It is especially helpful for baking where sugar directly affects browning, moisture, and texture, making rough estimates riskier than in other types of cooking.
Ingredient assumption
sugarThis sugar page is specific to granulated sugar and uses a standard kitchen assumption of roughly 200 grams per US cup. That makes it useful for baking and dessert prep, while still clearly signaling that weight-to-volume cooking conversions are approximate and ingredient-dependent.
Density note: 1 cup granulated sugar ≈ 200 g and 1 tsp sugar ≈ 4.2 g. This is an approximate kitchen reference, not a universal volume-to-weight rule for every ingredient.
When to use it
kitchen contextTurn weighed sugar into cup measures for quick baking prep.
Adapt metric dessert recipes for cup-based kitchen tools.
Estimate sugar volume without guessing from a dense ingredient.
Important note
approximateCooking conversions like cups to grams and grams to teaspoons depend on ingredient density, packing, humidity, and how the ingredient is measured. This page is locked to granulated sugar so the assumption stays clear and the result is less misleading than a universal converter.
