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
Walnuts (halves) has a density of 0.42 g/ml, which means it's very light — volume measurements can be especially misleading. Using weight-based measurements gives you consistent results every time.
Recipe Context for Walnuts (halves)
For seed gels: hydration ratio directly affects binding strength.
For toppings: weight gives consistent coverage and bake color.
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 walnuts (halves) = 100g. Real-world range can shift by about 9% because cut size, grind consistency, and oil content alter packing behavior.
Example for 2 cups: baseline 200g, common range 182g-218g. If your bake is texture-sensitive, start with the lower bound and adjust after a test batch.
