}Explanation
Rum (40% ABV) grams convert to fluid ounces by dividing through the verified 28.213 g/fl oz density anchored to the US fluid ounce (29.57 mL).
Use the calculator to translate weights into U.S. fluid ounce totals for menus or batch scaling.
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.
