Re: mega and gaga hertz
This is almost direct from my word processor. I hope it formats correctly. If not, you'll see a lot of crap crammed together. If so, I'll try again. In each area, a number similar to "10^12" is understood to be "ten to the minus twelfth power"

Metric Prefixes – Short, Practical List
T tera x10^12 x1,000,000,000,000
Example: terabytes (maybe by 2010)
G giga x10^9 x1,000,000,000
Example: 2.4 gigaHertz cordless phone; 20 gigabyte hard disk drive
M mega x10^6 x1,000,000
Example: 512 megabytes of memory; 94.5 megaHertz FM (KKLR)
K(k) kilo x10^3 x1,000
Example: 930 kiloHertz AM (KWOC)
–  x10^0 x1
m milli x10^3 x0.001
Example: 21.3 millimeters; 500 milliliters
m micro x10^6 x0.000 001
Example: 10 microfarad motor capacitor
n nano x10^9 x0.000 000 001
Example: 120 nanosecond RAM chip
p pico x10^12 x0.000 000 000 001
Example: 470 picofarads; 900 picoseconds
Quantities larger than 1 (positive powers of 10) have uppercase multipliers; numbers less than 1 (negative powers of 10) have lowercase multipliers. Internationally, kilo is usually written as lowercase making it an exception, but there's no reason to not use uppercase just to keep things simple to remember as "K" vs. "k" isn't otherwise used as a prefix. The Greek letter "m" is the only unusual letter used as a prefix and is formed by putting a descender on a lowercase "u" making "µ". In fact, in the days of typewriters, "u" was understood to be "µ" when used in the context of a prefix such as "27uF" meaning "27µF". Sometimes, the preceding descender was added by hand for more formal papers and the richer publishing houses actually used a true "mu". Two other commonlyused prefixes do not fit this "metric" list in that they do not use an integer multiple of 3 as a power: "d" for "deci" (x10^1) as in decibel and "c" for "centi" (x10^2) as in centimeter. This also means that centipede and millipede (100 and 1000legged bugs) are improper uses of the prefixes as they would really mean each only had one partial leg.

Re: mega and gaga hertz
OK. It was somewhat of a train wreck, but not as bad as I thought it was going to be. By the way, the short answer to your question is:
1000 MHz = 1 GHz
1000 MHz = 1 GHz

Boy, they really messed up dollars. Mille is thousand in French. One mil is 1/1,000 of an inch, but million means 1,000,000. If it were done right, million would be 1,000. Billion would be 1,000,000 (two sets of 3 zeros). Trillion would be 3 sets of 3 zeros. But Noooooo!
