Full API documentation

Explanation

Convert grams of beer into US fluid ounces using the same 29.87 grams-per-fluid-ounce reference used on the reverse page.

That is useful when serving notes, can or bottle sizes, and batch prep need beer volume and weight to stay aligned. Beer can vary a little with carbonation, sugar, and alcohol level, so the converter keeps one stable profile instead of swapping between product-specific labels.

Method & Density Basis

Density basis: 1.01 g/mL (anchored to US cup 236.588 mL and US fl oz 29.57 mL).
Applied factor: 1 Gram = 0.03 Fluid Ounces.
Consistency rule: mirror pages invert the same per-liquid constants so forward and reverse directions remain aligned.
Source: Beer density approximation (Beer density near room temperature.)

Methodology

Beer density evidence

Beer uses 1.01 g/mL in this dataset, which is 1.0% heavier by volume than the 1 g/mL water reference. Evidence status: medium-confidence. Source basis: Beer 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.
