Methodology·How We Verify

Snapshot

1 gram of white rum equals 1.05 milliliters. Conversion Encyclopedia keeps one fixed beverage basis on this page so the calculator, common values, and reverse page stay aligned.

Reference basis: 0.953 g/mL.
Example: 250 g = 262.33 mL.
This uses White Rum at 40% ABV (not pure ethanol), so density differs from alcohol-only references.

Use the interactive calculator below for custom values and the common-value table for quick checks.

Full API documentation

Explanation

Convert grams of white rum into milliliters using the same 0.953 g/mL density reference used on the reverse page.

That is especially useful for cocktail specs, batching sheets, and inventory work where white rum starts from weight but service still uses poured measures. White Rum is treated here as 40% ABV, so stronger or lower-proof bottles can shift the practical density slightly.

Method & Density Basis

Density basis: 0.953 g/mL (anchored to US cup 236.588 mL and US fl oz 29.57 mL).
Applied factor: 1 Gram = 1.05 Milliliters.
Consistency rule: mirror pages invert the same per-liquid constants so forward and reverse directions remain aligned.
Source: 40% ABV ethanol-water density approximation (Approx density for ~40% ABV ethanol-water at room temp (used across base spirits).)

Methodology

White Rum density evidence

White Rum uses 0.953 g/mL in this dataset, which is 4.7% lighter by volume than the 1 g/mL water reference. Evidence status: medium-confidence. Source basis: Approx density for ~40% ABV ethanol-water at room temp (used across base spirits).

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.
