1GHz is the same as 1000MHz, so 8GHz is 8000MHz.
Kilo = 1000
Mega = 1000*1000
Giga = 1000*1000*1000
Tera = 1000*1000*1000*1000
Peta = 1000*1000*1000*1000*1000
And so on.

1,000 KHz = 1 MHz
One cycle, in a computer, takes a time that is the reciprocal of the computer's clock rate - that which is expressed in MHz, or - more commonly nowadays - in GHz. Example: if your computer has a clock rate of 3 GHz, the time for a single cycle is (1 / 3 billion) seconds, i.e., 1/3 of a nanosecond, or 333 picoseconds.
It seems you are talking about radio waves. The wavelength (40 m) multiplied by the frequency (7 million / second) must equal the speed of light (300 million meters/second). It seems that in this example numbers, either the wavelength or the frequency, or both, are not expressed with a great accuracy. For example, if 40 meters is exact, the frequency would be close to 7.5 MHz.
400-470 mhz = -70
5 MHz = 1 second divided by 5.000.000 4.77 MHz = 1 second divided by 4.770.000
