Some of these name are rather long, such as\n    \"ThermodynamicTemperature\". Shorter alias names are defined, e.g.,\n    \"type Temp_K = ThermodynamicTemperature;\".</li>\n<li>Modelica units are defined according to the SI base units without\n    multiples (only exception \"kg\").</li>\n<li>For some quantities, more convenient units for an engineer are\n    defined as \"displayUnit\", i.e., the default unit for display\n    purposes (e.g., displayUnit=\"deg\" for quantity=\"Angle\").</li>\n<li>The type name is identical to the quantity name, following\n    the convention of type names.</li>\n<li>All quantity and unit attributes are defined as final in order\n    that they cannot be redefined to another value.</li>\n<li>Similar quantities, such as \"Length, Breadth, Height, Thickness,\n    Radius\" are defined as the same quantity (here: \"Length\").</li>\n<li>The ordering of the type declarations in this package follows ISO 31:\n<pre>\n  Chapter  1: <strong>Space and Time</strong>\n  Chapter  2: <strong>Periodic and Related Phenomena</strong>\n  Chapter  3: <strong>Mechanics</strong>\n  Chapter  4: <strong>Heat</strong>\n  Chapter  5: <strong>Electricity and Magnetism</strong>\n  Chapter  6: <strong>Light and Related Electro-Magnetic Radiations</strong>\n  Chapter  7: <strong>Acoustics</strong>\n  Chapter  8: <strong>Physical Chemistry</strong>\n  Chapter  9: <strong>Atomic and Nuclear Physics</strong>\n  Chapter 10: <strong>Nuclear Reactions and Ionizing Radiations</strong>\n  Chapter 11: (not defined in ISO 31-1992)\n  Chapter 12: <strong>Characteristic Numbers</strong>\n  Chapter 13: <strong>Solid State Physics</strong>\n</pre>\n</li>\n<li>Conversion functions between SI and non-SI units are available in subpackage\n    <strong>Conversions</strong>.</li>\n</ul>\n</html>"));
