Alcohol By Volume (ABV): 0.00%

Alcohol By Weight (ABW): 0.00%

Proof (US): 0.00

Total Pure Alcohol: 0.00 liters

          Selected Output:

Original Gravity (OG): The specific gravity reading before fermentation begins. Typical range: 1.030-1.120

Final Gravity (FG): The specific gravity reading after fermentation completes. Typical range: 0.990-1.020

Volume: The total volume of your beverage in liters.

Output Units: Choose between ABV (Alcohol By Volume), ABW (Alcohol By Weight), or Proof (US standard).

ABV is calculated using the standard formula: ABV = (OG - FG) × 131.25

ABW is approximately 80% of ABV: ABW = ABV × 0.79336

Proof is double the ABV: Proof = ABV × 2
