1 ounce of Granulated Sugar in cups

1 ounce of granulated sugar = 0.14 US cups. That's based on a 200 g per cup baseline. Because granulated sugar can shift with packing and crystal size, weighing is usually more accurate than measuring by volume.

What the sources say granulated sugar weighs

Published values, quoted at the exact measure each source lists. Sources round differently and assume different fill techniques — which is why they rarely agree to the gram.

CupOrGram standardizes on 200 g per cup (12 g per tablespoon, 4 g per teaspoon) and uses that single value on every page — how we reconcile the sources.

Why this conversion varies

Granulated Sugar can pack very differently depending on crystal shape and moisture.

  • Fine vs coarse crystals change how much fits in a cup.
  • Packed measurements can be much heavier than loose fills.
  • This page uses a consistent 200 g per cup baseline for repeatable conversions.

Why this conversion matters

Granulated Sugar directly affects sweetness, spread, and browning. A small conversion mismatch can shift texture and caramelization, especially in cookies and frostings.

Practical baking use

Standard white table sugar, the most commonly used sweetener in baking. Use this conversion for cookies, syrups, and frostings where sugar balance affects spread and set.

  • Packed and loose measurements are not interchangeable.
  • Adjust in small steps if your ingredient is unusually moist or dry.

FAQ

How much is 1 ounce of granulated sugar in US cups?

1 ounce of granulated sugar is 0.14 US cups using a 200 g per cup baseline.

Is 8 oz of granulated sugar the same as 1 cup?

1.1 cups — 8 oz by weight of granulated sugar is not 1 US cup. A cup of granulated sugar weighs 200 g (7.1 oz). Ounces on this page are weight, not fluid ounces — the "8 oz = 1 cup" rule only holds for water-like liquids.

Is it better to weigh granulated sugar for baking?

Usually yes. Weight-based measuring reduces shifts from packing and crystal size, so your results are more repeatable.

Recipe Context for Granulated Sugar

For cookies: sugar ratio drives spread and caramelization.

For cakes: sugar level affects tenderness and moisture retention.

For frostings: weight gives repeatable texture batch to batch.

Common Pitfalls

  • Switching brands without re-checking weight can change texture and bake time.
  • Using volume-only measurements for dense ingredients can overshoot recipe targets.
  • Packed vs unpacked sugar measurements are not interchangeable.

Brand Variance Example

Baseline on this page: 1 cup granulated sugar = 200g. Real-world range can shift by about 8% because granule size, packing, and moisture level shift how much sugar fits in a cup.

Example for 2 cups: baseline 400g, common range 368g-432g. If your bake is texture-sensitive, start with the lower bound and adjust after a test batch.
