This Page provides information about dBm (decibel milliwatts) Watt Calculator. Calculator allows to calculate the dBm from Watt (or mW) and back (Watt or mW from dBm) using the formulas:
Example: dBm=43.0103 <-> 20000 mWatt <-> 20 Watt

In the second formula from the top of the page shouldn’t it be “mW = Watt / 1000” (divided by, not times 1000)?
