<p>This page is only really interesting because it contains a Javascript
program.  You seem to have Javascript turned off, so it won't work very
well.

<h3>Background</h3>

<p>When you pass round or square wire through flat rolls it gets flatter
and longer, but it also gets wider.  You can exploit this to make thin
wire strip of almost any dimensions, but it&rsquo;s rather difficult to
predict the result.  That&rsquo;s what this calculator does.

<p>You specify the width and thickness of the strip you want, and the
program calculates what size round or square wire you should start with.
Additionally, if you specify the length of strip you need, it will
calculate the length of the input wire.

<p>The chances are that you don&rsquo;t actually have the required
thickness of round or square wire to start with, but you do have some
that&rsquo;s thicker.  Just enter the size of the round or square
initial stock that you do have and the program will calculate how much
of it you need to create the required starting size that you can then
roll down to the required thickness of strip.

<p>For best results, roll the strip in as few passes as you can handle.

<p>You can see the <a href="rolling-eqn.html">detailed equations</a>
used for this calculation if you're interested.

<h3>Use</h3>

<p>Boxes with light red or white backgrounds are entry boxes for you to
type in your requirements; boxes with dark red or grey backgrounds are
where the calculator puts its answers.  White and grey mean that the box
is showing useful information: an input box contains a valid number, for
example, and an output box has calculated a correct answer.  Red, on the
other hand, means that there&rsquo;s something wrong: either the
calculator can&rsquo;t understand what you&rsquo;ve typed in an input
box, or it&rsquo;s hit trouble &ndash; usually this means that some
necessary input is missing.

<p>You specify the width and thickness of the strip you want, and the
program calculates what size round or square wire you should start with.
Additionally, if you specify the length of strip you need, it will
calculate the length of the input wire.

<p>You can use whatever units you like, as long as they are consistent,
but you cannot use wire gauges.  If you use millimetres, the results
will be in millimetres; if you use inches, the results will be in
inches.  Whatever you use, the results are displayed to only 3 decimal
places.
