Converter Calculator
Explanation
Convert grams of rum into US fluid ounces using the same 28.18 grams-per-fluid-ounce 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.
