<hr><a name="_details"></a><h2>Detailed Description</h2>
A unit for measurement.
<p>
The <a class="el" href="classUnit.html" title="A unit for measurement.">Unit</a> class both represents a base unit and is the base class for other unit types. Base units are units defined as basis for other units. Meters and seconds are typical base units.<p>
For base units, a name is all that is needed. Base units do however normally have three different names defined for use in expressions - abbreviation (ex. "m"), singular ("meter") and plural ("meters"). <hr><h2>Member Function Documentation</h2>
