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

}Explanation
Light 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.
Light rum is a clear or very lightly colored rum produced from sugarcane byproducts, typically molasses. It is known for its clean, mild profile and is widely used as a base spirit in cocktails where freshness, balance, and mixability are prioritized over heavy barrel influence. Practical use: Light rum is primarily used as a base spirit in refreshing and citrus-driven cocktails. It is essential in classics such as the Mojito and Daiquiri, and it plays a central role in tropical drinks like the Piña Colada. Its clean structure allows other ingredients—fresh citrus juice, sugar, herbs, and fruit—to remain clearly defined, making it a foundational spirit in both classic and modern mixology. Composition and sensory context: Light rum presents a clean, lightly sweet profile with subtle notes of sugarcane, vanilla, and faint tropical fruit. It is generally low in oak influence and perceived heaviness, offering a smooth, neutral backbone that integrates easily with citrus, mint, and fruit-forward ingredients. Compared to aged or dark rums, its character is restrained, emphasizing clarity and drinkability rather than depth from maturation.
Light 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 Light Rum: medium-confidence. Dataset note: Approx density for ~40% ABV ethanol-water at room temp (used across base spirits).

Methodology
Light Rum density evidence
Light 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.
