 Dokumentacja modułu [zobacz] [edytuj] [historia] [odśwież]

Dedykowana uniwersalna wtyczka formatująca wartość cechy z wartością ilościową z opcjonalną jednostką.

Wtyczka obsługuje parametr format, w którym można wskazać identyfikator Wikidanych (Qnnnnn) określający jednostkę miary w jakiej ma być zaprezentowany wynik. Jeśli jest pusty to wyświetlana jest aktualna wartość wraz z jednostką.
