dBW and dBm

Since dBW is in the same logarithmic form as dB the two forms can actually be added to express the power out of a system in dBW.

We know that adding logs is the equivalent of multiplying factors.
Thus,
Power Out is     3dBW + 10dB = 13dBW

Can you answer??
What is 13dBW expressed in watts ?
