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.
