Black Rum Grams to Cups
Snapshot
1 gram of black rum equals 0.004435 cups.
- Reference basis: 0.953 g/mL.
- Example: 250 g = 1.11 cups (about 1 1/8 cups).
- This uses Black Rum at 40% ABV (not pure ethanol), so density differs from alcohol-only references.

}Explanation
Black Rum grams convert to cups by dividing through the verified 225.468 g/cup density anchored to the US cup (236.588 mL) definition.
Use the calculator to see how labeled weights translate into cups using the same density as the milliliter family.
Black Rum is a deeply colored rum style characterized by pronounced molasses richness, heavy body, and dark sweetness. Its intense color and flavor are often achieved through molasses concentration, blending, and the use of caramel coloring, rather than extended aging alone. Practical use: Black Rum is used as a rich, dark rum base and as a color-and-body modifier in builds that require depth, darkness, and molasses intensity. It is especially effective in ginger-based highball frameworks and other carbonated structures where its density can support float and layering techniques for visual contrast. It is also widely applied in layered rum blends and sweet-forward profiles where body and dark sweetness are central, as well as in culinary uses for its strong molasses character. Composition and sensory context: Black Rum presents a dense, molasses-driven profile with deep notes of treacle, burnt sugar, caramel, and dark toffee. It often shows a slight technical smokiness derived from burnt-sugar aromatics. The palate is heavy and rounded, with a coating, viscous mouthfeel that adds significant body to mixed drinks. Oak influence, when present, is typically secondary to sweetness and color, contributing soft vanilla or mild bitterness rather than bright structure.
Black Rum uses 0.953 g/mL in this dataset. That makes it 4.7% lighter by volume than water at the 1 g/mL reference. On the same basis, one US cup is about 225.5 g and one US fluid ounce is about 28.18 g.
Alcohol concentration affects density: a bottle with a materially different ABV can weigh differently for the same measured volume. These figures describe a reference conversion, not a guarantee for every brand, recipe, serving temperature, or production batch.
Evidence status for Black Rum: medium-confidence. Dataset note: Approx density for ~40% ABV ethanol-water at room temp (used across base spirits).

Methodology
Black Rum density evidence
Black Rum uses 0.953 g/mL in this dataset. Confidence: medium. Source basis: Approx density for ~40% ABV ethanol-water at room temp (used across base spirits).
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.
