-                <li>&#8960a : Conductor diameter in millimeters (mm).</li>
+                <li>&#8960a : Conductor diameter in millimeters (mm). Estimated equivalent AWG wire size is also displayed where appropriate.</li>
                 <li>&#8960b : Loop diameter in millimeters (mm).</li>
                 <li>c/a : 'c' is the inter-winding spacing, and 'a' is the conductor diameter, so 'c/a' is the spacing ratio. (Must be >= 1.1) 
                     A low-value will increase the proximity effect.</li>
