Simple vector math:

double accTotal = sqrt((accX * accX) + (accY * accY) + (accZ * accZ));

Is there any Formula for converting Acceleration to frequency ?

Doing so makes as little sense as converting acceleration to elephants per year.

Want to measure the vibration from accelerometer and counter act to vibration and nullify it

Then you have forgotten the most important parameter. You need to make your measurements at least twice as fast as the fastest vibration you expect.

how do I do that ?

How are you doing it now? Do it more often.
