Create Unit Codes and Relationships

Explanation

The purpose of this activity is define new types of units you need in your system. All attributes in use will have a unit connected. The system has a default set of units following the ISO standard. But you are also able to create new units. Examples of units are: Hours, Hz, MB, K, m/s, km/h etc.

For each unit you define you can also define derived units. For instance m/s is a derived unit from km/h. But in order to go from m/s to km/h you have to correct the value with a factor 3.6, i.e. m/s = 3.6 * km/h. If km/h is the unit and m/s is the derived attribute then the factor is 3.6. If m/s is the unit and km/h is the derived attribute then the factor is 0.2777.

Procedure

1. Enter unit code and description.
   Optional you can set a unit type. Possible values are: Not Used, Weight, Volume and Discrete.
   The User Defined value is automatically set by the system.
2. Save the changes.
3. Enter derived units. Select base unit code. Add derived unit codes together with a conversion factor.
4. Save changes.
