convert from dB to KW
As I understood, dB means lossy percentage of output power to input power ... 
for example, if a concrete wall has X dB, then that means that (for example) 0.79 of the input power survives.


the question here : is any possible way to convert dB to KW, and then say that concrete wall (in previeous example) decreases number of KWs of input power instead of percentage value ? 


I hope you understood me !


thanks
