dBm & Voltage Conversion Table
- conversion table to convert between dBm, Watts and voltage in a 50 ohm system.
Decibel tutorial includes
When working with RF power, it is often useful to know the voltage level for a given power.
The table below provides a chart to convert between dBm, watts and voltage - peak to peak in a 50Ω system.
Although voltage levels are unlikely to rise to significant levels which might cause damage for power levels measured in dBm, the voltages are often used in other calculations.
Three tables have been included. These have been chosen because the voltages move from readings measured in millivolts to those in volts. Also as the milliwatts change to watts, the change in the table is made.
dBm / millivolts / milliWatts conversion table
This conversion table charts the values for dBm against milliwatts and the relevant voltage expressed in millivolts.
It is applicable to many lower power applications.
dBm - milliwatts - Volts conversion table:-
This conversion table charts the values for dBm against milliwatts and the relevant voltage expressed in volts.
It is applicable to many medium power applications.
dBm - Watts - Volts conversion table
This conversion table charts the values for dBm against milliwatts and the relevant voltage expressed in volts.
It is applicable to many high power applications.
