Units and Measures

A unit is a quantity that is used as a standard of measurement. A measure is a component that is used to define a unit in XBRL. For example, the unit km/s (kilometers per second) contains two measures: kilometers and seconds. In CDM XBRL, you can define units and measures that are used for tagging.

A unit specifies what the amount reported represents. Units can be simple or complex.

• Simple Units
  For example, EUR (Euros), use the numerator.
• Complex Units
  For example, Earnings per Share, enter the currency in which the earnings are expressed (such as Euro) as the numerator and xbrli:shares as the denominator.

After you define the units that you want to use in tagging, you must associate them with a project. If you add a custom measure with no namespace, the measure adopts the target namespace of the taxonomy associated with the project in which it is used.

Important: Currencies such as EUR and USD are shown in ISO4217 currency standard form (for example, iso4217:EURO or iso4217:USD). A unit can consist of only a numerator, or consist of both a numerator and denominator. A unit cannot consist of only a denominator.
