description: 'An abbreviation for a unit is a short ASCII string that is used
in place of the full name for the unit in contexts where non-ASCII characters
would be problematic, or where using the abbreviation will enhance readability.
When a power of a base unit needs to be expressed, such as squares this can
be done using abbreviations rather than symbols (source: qudt)'
