Conversions

Conversions are rules that convert values from one unit to another. You can define unit form components with reference to other units, so that data can be displayed online as one unit and stored in the database, after conversion, as the other. For example, you can design a form so that a CRC can choose whether to enter a weight in kilograms or pounds and specify that the weight is always stored in the database in kilograms. The unit in which data is stored in the database after conversion is called the base unit, and the data value, after conversion to the base unit, is called the normalized value.

To perform conversions between the entered and base unit values, you create conversion rules and associate them with unit definitions.
