+<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.
