Convert 20 dBm to Watt - Decibel-milliwatt to Watt Calculator

A power level of 0 dBm corresponds to a power of 1 milliwatt. A 10 dB increase in level is equivalent to a ten-fold increase in power. Therefore, a 20 dB increase in level is equivalent to a 100-fold increase in power. A 3 dB increase in level is approximately equivalent to doubling the power, which means that a level of 3 dBm corresponds roughly to a power of 2 mW. Similarly, for each 3 dB decrease in level, the power is reduced by about one half, making −3 dBm correspond … WebThe benefit of expressing signal strength (power) in dBm is: we can express both very large and very small power values (W) in a short range of number.
