context_page_description: Units of alcohol are used in the United Kingdom as a measure to quantify the actual alcoholic content within a given volume of an alcoholic beverage, in order to provide guidance on total alcohol consumption.
  A number of other countries use the concept of a standard drink, the definition of which varies from country to country, for the same purpose. Standard drinks were referred to in the first UK guidelines that published "safe limits" for drinking, but these were replaced by references to "alcohol units" in the 1987 guidelines and the latter term has been used in all subsequent UK guidance.
  One unit of alcohol is defined as 10 millilitres of pure alcohol. Typical drinks may contain 1–3 units of alcohol.
  Containers of alcoholic drinks sold directly to UK consumers are normally labelled to indicate the number of units of alcohol in a typical serving and in the full container, as well as information about responsible drinking.
  As an approximate guideline, a typical healthy adult can metabolise about one unit of alcohol per hour, although this may vary depending on sex, age, weight, health and many other factors.
context_section_description: Units of alcohol are used in the United Kingdom (UK) as a measure to quantify the actual alcoholic content within a given volume of an alcoholic beverage, in order to provide guidance on total alcohol consumption.
  A number of other countries (including Australia, Canada, New Zealand, and the US) use the concept of a standard drink, the definition of which varies from country to country, for the same purpose.  Standard drinks were referred to in the first UK guidelines (1984) that published "safe limits" for drinking, but these were replaced by references to "alcohol units" in the 1987 guidelines and the latter term has been used in all subsequent UK guidance.
  One unit of alcohol (UK) is defined as 10 millilitres (8 grams) of pure alcohol. Typical drinks (i.e., typical quantities or servings of common alcoholic drinks) may contain 1–3 units of alcohol.
  Containers of alcoholic drinks sold directly to UK consumers are normally labelled to indicate the number of units of alcohol in a typical serving (optional) and in the full container (can or bottle), as well as information about responsible drinking.
  As an approximate guideline, a typical healthy adult can metabolise (break down) about one unit of alcohol per hour, although this may vary depending on sex, age, weight, health and many other factors.
