This document discusses conversion rates for different sized stock keeping units (SKUs) of alcoholic beverages. It notes that the standard conversion rate of 13/13.1 is not accurate for all SKUs as sizes and rates vary. Specific conversion rates are provided for different sized bottles and containers, from 60cl to 30cl. Examples are shown calculating the number of crates or cases contained in a hectolitre for different SKUs based on their individual conversion rates, derived from bottle size and number per crate. Understanding how the individual rates are derived can help sales align figures more accurately.
