rf

Convert a power level in dBm to milliwatts, watts, dBW, and RMS voltage across a given impedance. dBm is the standard unit for RF power referenced to 1 milliwatt. This tool is essential when interfacing datasheets (which use dBm) with circuit analysis (which uses volts and watts). Default impedance is 50 ohms, matching most RF systems. Use this to quickly verify power amplifier output, receiver sensitivity, or regulatory EIRP limits.
