how do i convert a vibration reading in dB and G's to Hz? This is reading of the floor slab on grade.

Furthermore, some ISO standards require the floor velocity in terms of a one-third octave spectrum. The amplitude in each band is represented in terms of RMS velocity.
This format is called "Generic Vibration Criteria (VC) for Vibration-Sensitive Equipment."

Try using 1 G for your reference level; in the eqn L = 20 log G's
That is, G's = 10^(dBg/20)

AdB is re: 1 micro g
then there's pk vs RMS, ISO vs ??

This one has a unit of "AdB" for acceleration and "VdB" for velocity in decibles.
