And when I started in the business it 3.33GHz was called 3.33 Kilo
Mega Cycles (kMC).
Looked around the web and got some hits. Back to 1955 where they are
talking about an X-Band radar (10 kMc).
A standard was to use a lowecase when referring to radio frequencies
(kHz) and I think an upper for computer rates kbs.
I think generally accepted that K always = 1000 except when talking
1 Kbs (kilo bits per second) is still 1000.
And the basis for such dimension-ordering: engineering-notation for the
exponent of 10, using increments of 3. (Vice plain scientific notation,
where the exponent can be any integer.)
Ex: Real number (coefficient) * 10^exponent, where exponent is an
integer in (... -12,-9,-6,-3,0,3,6,9,12, ...). And the coefficient is
normalized to be greater than or equal to 1 and less than 1000.
