This information is part of the Modelica Standard Library maintained by the Modelica Association.

This package provides predefined types, such as Angle_deg (angle in degree), AngularVelocity_rpm (angular velocity in revolutions per minute) or Temperature_degF (temperature in degree Fahrenheit), which are in common use but are not part of the international standard on units according to ISO 31-1992 "General principles concerning quantities, units and symbols" and ISO 1000-1992 "SI units and recommendations for the use of their multiples and of certain other units".

If possible, the types in this package should not be used. Use instead types of package Modelica.Units.SI. For more information on units, see also the book of Francois Cardarelli Scientific Unit Conversion - A Practical Guide to Metrication (Springer 1997).
