Full API documentation

Explanation

Convert US cups of whole milk to grams using a density reference of 1.03 g/mL. With the US cup fixed at 236.588 mL, that gives 243.69 grams per cup for this ingredient.

That is useful for dairy-style beverage prep, creamy mixers, and recipe work where whole milk may be scooped or poured but still needs a consistent mass reference. Whole milk can vary with fat level, thickness, and temperature, so the converter keeps one stable density reference for consistency.

Method & Density Basis

Density basis: 1.03 g/mL (anchored to US cup 236.588 mL and US fl oz 29.57 mL).
Applied factor: 1 Cup = 243.69 Grams.
Consistency rule: mirror pages invert the same per-liquid constants so forward and reverse directions remain aligned.
Source: Beverage density reference (Whole milk density near room temperature.)

Methodology

Whole milk density evidence

Whole milk uses 1.03 g/mL in this dataset, which is 3.0% heavier by volume than the 1 g/mL water reference. Evidence status: medium-confidence. Source basis: Whole milk density near room temperature.

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.
