Use this tab to view all units previously registered in IFS/Application Services. There are about 300 predefined units from the ISO Code lists. You can also define new units in this window. All entered units are connected to a base unit, i.e., a meter is the base unit for millimeter. The Factor field shows how to convert from a unit to its base unit, i.e., how many base units it will take to equal one unit. If a unit is a base unit itself, the same unit will be shown both in the Unit Code and the Base Unit fields. The Factor field will then contain the value one (1).
