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
Raisins has a density of 0.67 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 Raisins
For dried fruits: hydration level impacts chew and spread.
For fruit swaps: verify sweetness and acidity changes in the final bake.
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.
Brand Variance Example
Baseline on this page: 1 cup raisins = 160g. Real-world range can shift by about 7% because water content and texture vary by ripeness, processing, and brand.
Example for 2 cups: baseline 320g, common range 298g-342g. If your bake is texture-sensitive, start with the lower bound and adjust after a test batch.
