Modelica.Units.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.Units.NonSI to the corresponding SI Units defined in package Modelica.Units.SI 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 Modelica.Units.SI;
import Modelica.Units.Conversions.{from_degC, from_deg, from_rpm};
   ...
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).
