Why this conversion matters
Butter has a density of 0.911 g/ml, which means it's close to the density of water. Using weight-based measurements gives you consistent results every time.
Recipe Context for Butter
For creaming methods: weight keeps butter-to-sugar balance stable.
For custards: tight dairy ratios reduce curdling risk.
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.
- Butter and dairy temperature affects emulsion stability and spread.
Brand Variance Example
Baseline on this page: 1 cup butter = 227g. Real-world range can shift by about 6% because temperature and fat phase (solid vs softened vs melted) change effective volume.
Example for 2 cups: baseline 454g, common range 426g-482g. If your bake is texture-sensitive, start with the lower bound and adjust after a test batch.
