Frequently Asked Questions
dBm is decibels relative to 1 milliwatt (0 dBm = 1 mW), while dBW is decibels relative to 1 watt (0 dBW = 1 W). They differ by 30 dB: 0 dBm = -30 dBW.
Use the formula: P(dBm) = 10 * log10(P(W)) + 30. For example, 1 W = 10*log10(1)+30 = 30 dBm.
Yes, negative dBm values correspond to powers less than 1 mW. For example, -10 dBm = 0.1 mW.
