Voltage to dBm conversion.
The power level of radiofrequency energy is often expressed in decibels above one milliwatt.
This spreadsheet calculates the following:

The power in watt and dBm with a given voltage and impedance.

The power in dBm with a given power and impedance.

The voltage in millivolts with a given power and impedance.

The power in watt with a given power in dBm and impedance.

The voltage in millivolts with a given power in dBm and impedance.

Converts from millivolt to microvolt and volt.

Converts from watt to milliwatt.
