Key Terms for ABV Calculator

Term	Definition
Specific Gravity (SG)	A measure of the density of a liquid relative to the density of water. It is a dimensionless number used to determine the concentration of sugars in a liquid.
Original Gravity (OG)	The specific gravity of the unfermented liquid before fermentation starts. It indicates the potential alcohol content of the beverage.
Final Gravity (FG)	The specific gravity of the beverage after fermentation is complete. It helps determine the actual alcohol content by reflecting the remaining unfermented sugars.
Plato (°P)	A scale that expresses the concentration of extract (dissolved sugars) in a liquid as a percentage by weight. It is an alternative to specific gravity for measuring the sugar content in the unfermented liquid.
Standard Method	Formula: ABV = (OG−FG) × 131.25. Basic method to calculate ABV using hydrometer readings.
Standard+ Method	Formula: ABV = (OG−FG) × 132.715. An improved version of the standard hydrometer method for better accuracy.
Advanced Method	Formula: ABV = 76.08 × (OG−FG) / (1.775-OG) × (FG/0.794). A more complex formula that takes into account the density changes during fermentation.
