How may seconds in a kilometer?
Same thing. Hertz measure frequencies, decibel measure power. Not the same thing at all.

How many apples in an orange?
Figure out how to use a search engine and go look up what 'decibels' and 'megahertz' are and you won't appear quite so stupid in public.

Decibels is determined by waveform shape. Frequency does not matter as much as duty cycle. The following site provides insite into decibels and sound pressure: http://www.a2dvoices.com/realitycheck/dbSPL/

A decibel is a unit of measurement for power levels, and can not be related to a frequency. It relates to units of watts or milliwatts.

None. Decibels are a way to measure volume of sound. Hertz measure the amplitude which is the pitch.

decibel is strength of the sound. herz are the frequency of hte sound, or the number of vibrations per second. they are two completely different things.
if you draw sound as waves, then decibel, or intensity ofhte sound is the height of the waves. the herz are the number of waves per second.
