Rum Grams to Milliliters

Updated: March 1, 2026 · Source: 40% ABV ethanol-water density approximation (Approx density for ~40% ABV ethanol-water at room temp (used across base spirits).)

Snapshot

1 gram of 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 Rum at 40% ABV (not pure ethanol), so density differs from alcohol-only references.

With 1 gram of Rum, you get just a small pour.

Explanation

Convert grams of 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 rum starts from weight but service still uses poured measures. 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.
