Standard language
Defines which unit is to be used in a unit class if a language is set at runtime for which no unit has been configured.
Example
The metre/inch unit is to be switched at runtime depending on the language (project languages German/English (USA)/ French/ Italian). Two units are projected in the corresponding unit class:
1st German (switching code: 1031)
2nd English (switching code: 1033)
The default language is set to 1031. This means that the unit conversion configured for the German language is automatically used when switching to French/Italian at runtime.
