}Explanation
US cups convert to grams by multiplying with the verified 243.7 g/cup density derived from the US cup (236.588 mL) definition and the liquid’s grams-per-milliliter ratio.
Use the calculator to translate recipe cups into grams while keeping the same density that powers the milliliter and fluid ounce families.
Whole milk uses 1.03 g/mL in this dataset. That makes it 3% heavier by volume than water at the 1 g/mL reference. On the same basis, one US cup is about 243.7 g and one US fluid ounce is about 30.46 g.
Fat, protein, and dissolved solids vary across dairy-style products, so formulation and temperature can shift the measured density. These figures describe a reference conversion, not a guarantee for every brand, recipe, serving temperature, or production batch.
Evidence status for Whole milk: medium-confidence. Dataset note: Whole milk density near room temperature.

Methodology
Whole milk density evidence
Whole milk uses 1.03 g/mL in this dataset. Confidence: medium. Source basis: Whole milk density near room temperature.
Evidence status: reference-recorded. The source note is recorded; this does not certify every preparation or measurement condition.
Brand formulation, alcohol or sugar concentration, carbonation, and serving temperature can change the weight of a measured volume. Use this value as a documented reference rather than a producer specification.
