<p>The UDUNITS-2 package provides support for units of physical quantities.
Its three main components are: 1) <a href="udunits2lib.html#Top">(udunits2lib)a C library</a>
for units of physical quantities;
2) <a href="udunits2prog.html#Top">(udunits2prog)a utility</a>;
for obtaining the definition of a unit and for
converting numeric values between compatible units;
and 3) an <a href="#Database">extensive database of units</a>.

<a name="How-This-Package-Differs-from-the-Original-UDUNITS-Package"></a>
<h2 class="chapter">2 How This Package Differs from the Original <code>UDUNITS</code> Package</h2>

<p>The <code>UDUNIT-2</code> package differs from the <code>UDUNITS-1</code>
package in the following ways:
</p><ul>
<li> <strong>Support for non-ASCII characters:</strong>  
The <code>UDUNITS-1</code>
package only supports the ASCII character set.  The <code>UDUNITS-2</code>
package supports the following character sets: ASCII, ISO 8859-1 (Latin-1),
and the UTF-8 encoding of ISO 10646 (Unicode).  This means that unit
string specifications like &quot;<code>ÂµÂ°FÂ·Î©â»Â¹</code>&quot; are now supported (your
viewer must support UTF-8 to display this string correctly).

</li><li> <strong>Support for logarithmic units:</strong>  The unit string
specification &quot;<code>0.1 lg(re 1 mW)</code>&quot; specifies a deciBel unit with a
one milliwatt reference level.
Such units are fully integrated into the package and all meaningful
operations and conversions are supported.

</li><li> <strong>Persistent value converters:</strong>
It is now possible to obtain a <em>converter</em> data-object, which can
be used to convert numeric values in one unit to numeric values in another,
compatible unit.  The values can be <code>float</code>, <code>double</code>, or
one-dimensional arrays of <code>float</code>s or <code>double</code>s.

</li><li> <strong>Improved API:</strong>  Due to the above changes, it was not
possible to keep the application programming interface (API) of the
<code>UDUNITS-1</code> package.  The new interface, however, is easily
understood and easy to use.  To support backward comptibility,
the package does contain a version 1 C API, which uses the version 2
library.

</li><li> <strong>XML unit database:</strong>  The unit database is encoded using
human-readable XML rather than a custom format.  The XML
parser included in the package supports an <em>&lt;import&gt;</em> element to
allow easy and convenient customization.

</li><li> <strong>No Fortran or Perl API:</strong>  Interfaces for these languages
have not yet been created.  Contact
<a href="mailto:support-udunits@unidata.ucar.edu">support-udunits@unidata.ucar.edu</a> if you are interested in
helping to create these interfaces.

</li></ul>

<p>One thing that has not changed is that almost all unit string specifications
understood by the <code>UDUNITS-1</code> package are also
understood by the <code>UDUNITS-2</code> package.  One exception is
the symbol <code>g</code>, which in version 1 of the package was associated with
standard free fall (a unit of acceleration) but which is associated
with the unit gram in version 2 of the package.

<p>If this package is to be tested (which is optional), then the CUnit library
