dBm
“dBm” is a unit that expresses the power of a signal on a logarithmic scale, using milliwatts (mW) as the reference point. Unlike dBV, which is based on voltage, dBm pertains to power and represents the power at a specific load impedance of 600 ohms. Since dBm indicates the relative strength of a signal, it can be both positive and negative; 0dBm corresponds to 1 milliwatt. dBm is widely utilized in measuring and conveying the strength of signals in electronic equipment and communication systems
