1/2 Cup of Different Ingredients — Weight Comparison

1/2 cup of different ingredients varies widely in weight because each has a different density. This matters when substituting ingredients in recipes.

Measuring Granulated Sugar Accurately

Why weight matters: 1/2 cup of granulated sugar can weigh anywhere from 85g to 120g depending on how you measure it. The USDA standard is 100g (spooned and leveled). Scooping directly from the container can add 10–20% extra weight, which affects recipe results — especially in baking.

About granulated sugar density: Granulated white sugar is the most consistent of all sugars — 1 cup = 200g regardless of spooning or packing. The uniform crystal size makes it very consistent to measure. Standard sugar for most baking recipes.

About 1/2 Cup as a Measurement

1/2 cup (120ml) is the most common single-serving measurement in baking. It equals 8 tablespoons or 24 teaspoons. Most standard muffin recipes call for 1/2 cup of flour per 6 muffins.

Half cup is a standard baking unit used in muffins, quick breads, pancakes, and cookie doughs. It represents exactly half of a US standard measuring cup (240ml).

Frequently Asked Questions

How many grams is 1/2 cup of granulated sugar?

1/2 cup of granulated sugar weighs 100 grams (3.53 oz, 120ml). Based on USDA FoodData Central: 1 cup granulated sugar = 200g, so 1/2 cup = 200 × 0.500 = 100g.

Is 1/2 cup of granulated sugar the same weight every time?

The weight can vary slightly depending on measuring technique. Spooned and leveled gives 100g. Scooped (packed) can be 10–20% heavier. Sifted gives a lighter weight. The USDA standard (spooned and leveled) of 100g is the most reliable baseline for recipes.

How do I accurately measure 1/2 cup of granulated sugar?

For accuracy, use a kitchen scale and weigh 100g of granulated sugar. If using measuring cups, spoon the granulated sugar lightly into a 1/2 Cup measuring cup and level off the top with a straight edge. Avoid scooping directly from the container, which compacts the ingredient and adds extra weight.

How does 1/2 cup of granulated sugar compare to other ingredients?

1/2 cup of different ingredients varies significantly: Powdered Sugar = 60g, Granulated Sugar = 100g, Caster Sugar = 105g. This is because each ingredient has a different density.
