RF Power Converter


This calculator will convert RF power in watts to decibels (dBW and dBm) and decibels into watts.


Inputs
Power
dBW
dBm
W

Equations

$$P \text{ in dBW} = 10 \log_{10}( P \text{ in W})$$

$$P \text{ in dBm} = 10 \log_{10}( P \text{ in mW}) = 10 \log_{10}(( P \text{ in W})\times1000)$$

$$P \text{ in W} = 10^{(( P \text{ in dB})/10)}$$

$$P \text{ in dBW} = (P \text{ in dBm}) - 30$$

where:

P = power

dBm = decibel-milliwatts

dBW = decibel-watts

mW = milliwatts

W = watts

 

Application

These calculations can be used when you need to calculate power losses and gains between a transmitter and a receiver.
