Science Note: Precision within +/-0.002g
Accuracy: +/-0.002gHow this is calculatedWe multiply the volume by the ingredient's specific density (g/ml) from NIST-standardized reference data. This accounts for how tightly each ingredient packs, giving accuracy within +/-0.002g.Source: NIST-DB-72
Why this conversion matters
Powdered Sugar has a density of 0.56 g/ml, which means it's moderately light — a cup weighs less than you might expect. Using weight-based measurements gives you consistent results every time.
Recipe Context for Powdered Sugar
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 powdered sugar = 120g. 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 240g, common range 220g-260g. If your bake is texture-sensitive, start with the lower bound and adjust after a test batch.
