dbm se yon pouvwa ke valè a absoli nan inite yo, fòmil la kalkil se: 10lg valè pouvwa / 1mW. Pou egzanp: Si pouvwa a transmisyon nan 1mW, dapre inite dbm apre valè a konvèsyon ta dwe: 10 lg 1mW / 1mW = 0dBm; pou 40W ki gen pouvwa, Lè sa a, 10 lg (40W / 1mW) = 46dBm.

dBm is a power that the absolute value of the units, the calculation formula is: 10lg power value / 1mW. For example: If the transmission power of 1mW, according to dBm units after the conversion value should be: 10 lg 1mW/1mW = 0dBm; for 40W of power, then 10 lg (40W/1mW) = 46dBm.
