The following converter are integrated: Längenumrechner, Weight converter, Temperaturumrechner, Geschwindigkeitsumrechner (Speedumrechner) Volumenumrechner, Druckumrechner and Zeitumrechner.
If something is missing or something is not clear or perhaps wrong somewhere, I am also happy about a message.
