Conversion of transmitter power from Watts into dB
  1. How do you convert watts to dB power?
  2. How do you calculate power to dB ratio?
  3. How many dB is a watt?

How do you convert watts to dB power?

Since Watts are proportional to Amps squared or Volts squared, db (in power) = 20 log V1/V0 or db = 20 log I1/I0 .

How do you calculate power to dB ratio?

The Decibel explained

The exact relationship is given by the formula Bels = log(P2/P1) , where P2/P1 represents the power ratio. With the constant almost always included in modern terminology and power referred to as a “ten log” function.

How many dB is a watt?

One watt=90 dB. One hundred watts, or 100X more power=110 dB.
