Liters of Absolute Alcohol by Weight Calculator
What this calculator does
The Liters of Absolute Alcohol by Weight calculator determines the LAA from the weight of spirits and the density at 20°C. It uses the CRA alcohol table to convert between weight, volume, and alcohol content. This method is used when spirits are weighed rather than measured by volume, which is common in some international production and reporting systems.
How to use it
Enter the net weight of the spirits and the density at 20°C. The calculator uses the CRA alcohol table to determine the ABV from the density, then calculates the volume and liters of absolute alcohol. Use a calibrated scale and density meter for accurate results.
Calculation notes
The CRA alcohol table provides the relationship between density at 20°C, alcohol by volume, and alcohol by mass. The calculator first looks up the ABV from the density, then converts the weight to volume using the density, and finally calculates the LAA. For fractional density values, interpolation is used. Always verify results using approved methods for regulatory purposes.
