David, your links have been truncated somehow and don't work.
Try http://www.mwlist.org/mwlist_quick_and_easy.php?area=1&kHz=927 (which is the site I used) and http://www.unitconversion.org/unit_conve...ength.html for the conversion.
Mind you, I find it is much simpler to work it out myself! Divide the known quantity into the speed of light (300,000,000m/s) although, as you usually have a good idea of the approximate result, just divide into 3 with as many zeros as you need to get a sensible result. In any case, I can open up the Windows calculator and get the answer faster than fiddling about selecting input and output parameters on a web page!
Good point about 930kHz - the same applies to 940kHz (2 x 470kHz) as well. I don't think anyone would have trouble with the US 455kHz option because it's been causing interference with reception of BBC stations on 908/9kHz since the earl 60s!
