Or was this just some convention I : learned somewhere that I mistakenly thought of as an actual accepted : rule? This is wrong. k is Si for 10^3, but m is 10^-3. M is 10^6 and G is 10^9. K was used for a long time for 2^10. M and G were overloaded to mean 2^20 and 2^30, but some people even in the industry broke ranks (the disk drive makers) and were able to claim larger disk sizes by using the Si meaning of M rather than the CS meaning of M. I've rarely seen your meanings used anywere, except for the k vs K thing. You may want to take a look at http://physics.nist.gov/cuu/Units/binary.html for definitions of the binary stuff.
