Light Rum Cups to Grams
Snapshot
1 cup of light rum equals 225.47 grams.
- Reference basis: 0.953 g/mL.
- Example: 2 cups = 450.94 g.
- This uses Light Rum at 40% ABV (not pure ethanol), so density differs from alcohol-only references.

}Explanation
US cups convert to grams by multiplying with the verified 225.5 g/cup density derived from the US cup (236.588 mL) definition and the liquid’s grams-per-milliliter ratio.
Use the calculator to translate recipe cups into grams while keeping the same density that powers the milliliter and fluid ounce families.
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.
