With 1 gram of Black Rum, you get < 0.01 cups, which is too little to measure reliably in a cup.

Explanation

Convert grams of black rum into US cups using the same 225.47 grams-per-cup reference used on the reverse page.

That is especially useful for cocktail specs, batching sheets, and inventory work where black rum starts from weight but service still uses poured measures. Black 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 = < 0.01 Cups.
  • Consistency rule: mirror pages invert the same per-liquid constants so forward and reverse directions remain aligned.
  • Source: Beverage density pool (Approx density for ~40% ABV ethanol-water at room temp (used across base spirits).)
