100 grams of granulated sugar = 0.50 cups (½ cup / 8.0 tbsp / 24.0 tsp)

Granulated Sugar has a density of approximately 200g per cup. Very consistent across brands. Source: USDA FoodData Central. This is the figure used everywhere on this page, including the tablespoon and teaspoon values, so the numbers stay consistent whether you're reading the summary line, the table, or the FAQ answers below.

How the 100g Figure Is Calculated

cups = grams ÷ grams per cup

100g divided by 200g (the weight of one cup of granulated sugar) equals 0.50 cups. Multiplying that by 16 gives 8.0 tablespoons, and by 48 gives 24.0 teaspoons, since one cup always equals 16 tablespoons or 48 teaspoons regardless of the ingredient.

Granulated Sugar is lighter than water, which weighs about 236g per cup. That's why 100g of granulated sugar takes up more volume (118ml) than the same weight of water would (100ml). For a side-by-side look at how other ingredients compare, see the 100 grams to cups page.

If Your Recipe Uses Metric or Imperial Cups

The 0.50 cup figure above uses the US Customary cup (236.588ml). Recipes written outside the US sometimes use a metric cup (250ml) or an imperial (uk) cup (284.131ml) instead. At 100g, that's ½ metric cups or ⅜ imperial cups of granulated sugar, close to the US figure but not identical. The cup standard switch in the converter above recalculates this instantly for any gram amount.

Scaling 100g Up or Down

Doubling a recipe that calls for 100g of granulated sugar means weighing 200g, or measuring 1.00 cups if you're working by volume instead of weight. Halving it means 50g, or 0.25 cups. Weight scales exactly with simple multiplication; cup measurements compound any scooping error each time they're doubled or halved, so weighing is more reliable the more a recipe is scaled.

Granulated Sugar vs. Other Sugars & Sweeteners

Within sugars & sweeteners, density still varies by ingredient. At 100g, brown sugar (220g per cup) measures ½ cup, while powdered sugar (120g per cup) measures ⅞ cup, compared to ½ cup for granulated sugar. Swapping ingredients in a recipe by cup measurement alone, without adjusting for this difference, changes the actual weight used.

Frequently Asked Questions

What is 100 grams of granulated sugar in cups?+

100 grams of granulated sugar is 0.50 cups (½ cup), or 8.0 tablespoons.

How do I measure 100 grams of granulated sugar without a scale?+

Use ½ cup, spooned in and leveled off with a straight edge. If you only have tablespoons, use 8.0 tablespoons instead.

Why is granulated sugar's gram-to-cup ratio different from other ingredients?+

Granulated Sugar weighs 200g per cup because of its own density. Very consistent across brands.

Does a metric or imperial cup change this 100g conversion?+

Yes, slightly. 100g of granulated sugar is ½ metric cups or ⅜ imperial cups, versus ½ US cups, since each cup standard holds a different volume.
