Modelica.SIunits.Conversions

Conversion functions to/from non SI units and type definitions of non SI units

Information


This package provides conversion functions from the non SI Units defined in package Modelica.SIunits.Conversions.NonSIunits to the corresponding SI Units defined in package Modelica.SIunits and vice versa. It is recommended to use these functions in the following way (note, that all functions have one Real input and one Real output argument):

  import SI = Modelica.SIunits;
  import Modelica.SIunits.Conversions.*;
     ...
  parameter SI.Temperature     T   = from_degC(25);   // convert 25 degree Celsius to Kelvin
  parameter SI.Angle           phi = from_deg(180);   // convert 180 degree to radian
  parameter SI.AngularVelocity w   = from_rpm(3600);  // convert 3600 revolutions per minutes
                                                      // to radian per seconds

Extends from Modelica.Icons.Package (Icon for standard packages).
