Hey Dan:

your getting way to technical for this group,  we still have trouble 
converting Litre's to flatted Fifths.  :))


P.S.  if you switch from Beer to a Flatted fifth or two your Back will 
feel a lot better quicker and you'll be out shakin yo bootie by 
tomorrow night,  heck maybe even tonight  since it is Sattidy  in 
Texas.  :))

Cheers,

Tom Wiggins

   Bob and DJML-- 
    Never mind. I mis-read 'C' as 'A'. Middle C is indeed 261.63 cps or 
Hz. 
    However, on the web i did find a page purporting to tell one how to 
convert from cps to Hz: 
 
  "In the mid-60's, The world converted to frequency measurements in 
Hertz. Abbreviated, it is Hz. The change was to honor Heinrich Hertz. 
If you still have magazines and books describing frequency in Cycles 
per Second or Megacycles, you will want to convert those numbers to Hz 
(Hertz) or MHz (Megahertz). To do that, use the chart above that was 
graciously provided by long time ham, Jim Barry WØIRE. To do it 
mathematically, multiply the frequency in cycles per second by cycles 
per second and then take the square root of the result." 
   (http://www.brainerdham.org/Tips/CPS_to_Hz_conversion.html) 
 
   Eh, wot? Why not just measure your tibia and divide by two?
