I think we should all use hexidecimal.  Or binary :)

I tell my electronics students that we can express gain or loss in dB by taking the log of power ratios and multiplying by 10, or by taking the log of the voltage or current ratios and multiplying by 20.

If we multiply the log by 16 instead, then the result is expressed in hexadecibels. :-)

("Hexabels" sounds too much like a made-up word.)
