Full API documentation

Explanation

Convert US fluid ounces of orange juice to grams using a density reference of 1.045 g/mL. On that basis, 1 US fluid ounce works out to 30.9 grams for this ingredient.

That is useful for juice prep, batching, and packaging work where orange juice may be recorded by volume in one step and by weight in another. Orange juice can vary with pulp, sugar, and concentrate level, so the converter keeps one reference value for repeatable conversions.

Method & Density Basis

Density basis: 1.045 g/mL (anchored to US cup 236.588 mL and US fl oz 29.57 mL).
Applied factor: 1 Fluid Ounce = 30.9 Grams.
Consistency rule: mirror pages invert the same per-liquid constants so forward and reverse directions remain aligned.

Methodology

Orange juice density evidence

Orange juice is a non-alcoholic citrus juice pressed from fresh oranges. It delivers natural sweetness with moderate but structurally relevant acidity and is widely used in cocktails, long drinks, punches, and non-alcoholic beverages to provide brightness, body, and balance.

Practical use: Orange juice functions as a primary citrus component in both alcoholic and non-alcoholic drinks. It is central to classics such as the Screwdriver and Mimosa, and it appears frequently in brunch cocktails, long drinks, punches, tropical serves, and mocktails. Its natural sugar content and moderate acidity allow it to bridge distilled spirits and acidic elements, making it ideal for larger-volume, easy-drinking constructions.

Composition and sensory context: Orange juice offers a bright, sweet citrus profile supported by moderate acidity and a soft, rounded mouthfeel. While less sharp than lemon or lime juice, its natural acidity still plays a significant role in cocktail balance. Freshly squeezed juice displays greater aromatic complexity and a subtle bitterness derived from peel oils and fruit membranes released during pressing, adding depth beyond simple sweetness.

Orange juice uses 1.045 g/mL in this dataset, which is 4.5% heavier by volume than the 1 g/mL water reference. Evidence status: medium-confidence. Source basis: Orange juice typical density.

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.
