.Modelica.SIunits

Information

This package provides predefined types, such as Mass, Angle, Time, based on the international standard on units, e.g.,

   type Angle = Real(final quantity = "Angle",
                     final unit     = "rad",
                     displayUnit    = "deg");

Some of the types are derived SI units that are utilized in package Modelica (such as ComplexCurrent, which is a complex number where both the real and imaginary part have the SI unit Ampere).

Furthermore, conversion functions from non SI-units to SI-units and vice versa are provided in subpackage Conversions.

For an introduction how units are used in the Modelica standard library with package SIunits, have a look at: How to use SIunits.
