}Explanation
Calculation basis: the recorded grams-per-US-cup value.
Butter (Unsalted) uses a recorded reference of 227 grams per US cup in this dataset. Confidence: high. Source basis: USDA (1 cup butter ≈ 227g)
Evidence status: reference-recorded. The source note is recorded; this does not certify every preparation or measurement condition. Temperature and physical state affect pourability and volume, so softened, melted, and solid forms should not be treated as interchangeable.

Questions & answers
Frequently Asked Questions
Does this use a US cup?
Yes. The factor is tied to the US cup definition (236.588 mL), not a metric cup.
Does temperature or physical state change the result for Butter (Unsalted)?
Butter (Unsalted) keeps one liquid-state reference basis here, but the result assumes the ingredient is melted or fully liquid when measured. Solid pieces, scooped chunks, or semi-solid fills do not behave the same way in a cup.
