The formulas
- Pure alcohol in grams = volume in ml × alcohol % ÷ 100 × 0.789 (the density of ethanol).
- Calories = alcohol grams × 7 + sugar grams × 4. Sugar grams = residual sugar g/L × volume ÷ 1000.
- A US standard drink is 14 g of alcohol. A UK unit is 8 g. Australia uses 10 g.
- Ounces are US fluid ounces at 29.57 ml each.
These figures follow the standard nutrition values for ethanol and sugar. A real bottle varies with its exact alcohol and sugar, so treat the results as close estimates.
