dB / Watts / ERP / EIRP Calculator

Convert dBWatts to Watts

Enter Value (dbW) : dBWatts = Watts

Convert Watts to dBWatts

Enter Value (Watts) : Watts = dBW

Calculating ERP and EIRP

 
Enter the Transmitter Power Output (TPO) : 
Enter the Antenna Gain : 
Effective Radiated Power (ERP) =  dBW = Watts
Effective Isotropic Radiated Power (EIRP) =  dBW = Watts
