A unit dictionary is a collection of related units of measurement (for example, inches and centimeters are related to length because they are both measurements of length). A unit dictionary is associated with a data point or field. Once a unit dictionary is associated with a field, a user can, within the EDC module, enter a numeric value and select from the values within the unit dictionary.
From the values created in the Unit Dictionary, one of the values serves as the standard value. Therefore, regardless of the unit of measurement selected by the user, all values will be converted to a standard value so that there is one common unit. Users can also set default units for each locale in the Unit Dictionary.
