Can anyone give me the equation to convert watts to Decibels?

No, because there isn't one. Watts is power, decibels is sound intensity.
While related, they are not the same thing: A higher wattage speaker will be
louder, but distance from the speaker matters, too.

from some web site I found:

"Another rule of thumb that is useful to remember is that 10 dB is a power
ratio of 10. Any time a power is increased tenfold, it is increased by 10 dB;
thus, a 200W power amplifier will put out 10 dB more electrical power than a
20W amplifier, and its sound power output will also increase by 10 dB."

But, it still can't say what the decibel level is in absolute terms.....
