How do you convert watts to dBm?
Decibels are used to represent the ratio of two quantities of power: db = 10 log P1/P0 . In the case of dbm the reference power P0 is 1 milliwatt : dbm = 10 log P1/1mw. Inverting this equation gives the power in terms of the reference power: P1= P010db/10….Decibels and dbm.
