<b>Function</b>
<dd>
Converts internal units.
<p>
<dt>
<b>Syntax</b>
<dd>
<tt>real u2inch(int n);</tt><br>
<tt>real u2mic(int n);</tt><br>
<tt>real u2mil(int n);</tt><br>
<tt>real u2mm(int n);</tt>
<p>
<dt>
<b>Returns</b>
<dd>
<tt>u2inch</tt> returns the value of <tt>n</tt> in <i>inch</i>.<br>
<tt>u2mic </tt> returns the value of <tt>n</tt> in <i>microns</i> (1/1000mm).<br>
<tt>u2mil </tt> returns the value of <tt>n</tt> in <i>mil</i> (1/1000inch).<br>
<tt>u2mm </tt> returns the value of <tt>n</tt> in <i>millimeters</i>.

<p>
EAGLE stores all coordinate and size values as <tt><a href=156.htm>int</a></tt>
values with a resolution of 1/10000mm (0.1µ). The above unit conversion
functions can be used to convert these internal units to the desired
measurement units.
<p>
<b>Example</b>
<pre>
board(B) {
B.elements(E) {
printf("%s at (%f, %f)\n", E.name,
u2mm(E.x), u2mm(E.y));
}
}
</pre>
