If you want to use a spread sheet – you can use the following formula

=POWER(10,A1/10)

Where A1 is the cell containing the value of the dBm.

The Chart presents the conversion of the dbm into Watts/Milliwatts. The Unit has been automatically adjusted to watts, milliwatts, uWatts ( microwatts), nanowatts and Pico Watts as required.

    It is interesting to note that the numerical value remains constant along the horizontal. Only the unit changes.

    Thanks for putting it up together.
