dbm se yon valè absoli nan di inite pouvwa, se kalkile kòm: 10lg pouvwa valè / 1mW. Pou egzanp: Si pouvwa a emetè nan 1mW, dapre inite dbm apre valè a konvèsyon yo ta dwe: 10 LG 1mW / 1mW = 0dBm, paske 40W ki gen pouvwa, Lè sa a, 10 LG (40W / 1mW) = 46dBm.

dBm is an absolute value of said power unit, is calculated as: 10lg power value / 1mW. For example: If the transmit 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.
