Perhaps you could create a user defined function. I'm sure there are plenty
of people here who would be willing to help if you post the formula for the
conversion.

I am constantly converting power between "watts" and "dBm" or "watts" and
"dBW" and back again. I believe that anyone in the RF & Microwave
business
does the same. Please add these units to the Convert worksheet function.
