Power Level Changes...

The number of dB difference between one power level and another is not always obvious. How much attenuation is required to lower one power level to another? How much gain is added when increasing from one power level to another? See below!

NOTE:  Units of power MUST be selected before the calculator will provide results (change numerical entries as desired).

(1) Select units of beginning power level:
 mW    W    dBm    dBW
(2) Highlight "1" in left-hand field, enter begining power level:  
(3) Select units of final power level:
 mW    W    dBm    dBW
