2^x=1000/68 gives me x=3.878321.I think this is the easier way to look at this mathematical problem. Say, Amir measured XYZ mVrms/94 dB SPL. So, how many dB is XYZ mV below 1 V? Answer is 20*log10(1000/XYZ). Add 94 to that and we have our dB SPL/Vrms sensitivity.
I tried your method (first step), doesn't seem correct (or may be I've missed something).

that times 6 equals 23.269926.
plus 94 makes 117.269926 [dBSPL/Vrms].
Your method gives nearly the same result, but in a more elegant way.
Thanks!
