Rum (40% ABV) Grams to Cups
Snapshot
1 gram of rum (40% abv) equals 0.004431 cups.
- Reference basis: 0.954 g/mL.
- Example: 250 g = 1.11 cups (about 1 1/8 cups).
- This uses Rum (40% ABV) at 40% ABV (not pure ethanol), so density differs from alcohol-only references.

}Explanation
Rum (40% ABV) grams convert to cups by dividing through the verified 225.705 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.
Rum (40% ABV) uses 0.954 g/mL in this dataset. That makes it 4.6% lighter by volume than water at the 1 g/mL reference. On the same basis, one US cup is about 225.7 g and one US fluid ounce is about 28.21 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 Rum (40% ABV): medium-confidence. Dataset note: Rum density near 40% ABV.

Methodology
Rum (40% ABV) density evidence
Rum (40% ABV) uses 0.954 g/mL in this dataset. Confidence: medium. Source basis: Rum density near 40% ABV.
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.
