RF Power Converter
Enter any power or voltage value to instantly convert between dBm, dBW, Watts, milliwatts, and voltage.
What is RF power conversion?
Just like converting miles to kilometers, RF engineers convert between different ways of describing the same power. dBm, watts, and volts all describe how strong a signal is — just in different units that suit different situations.
Why does this matter?
When your phone's WiFi specification says "20 dBm transmit power," that's just 100 milliwatts — less than a dim night light. The dBm scale makes it easy to work with both tiny receiver signals (−100 dBm) and large transmitter powers (40 dBm) without writing lots of zeros.
