DB ↔ Watts Calculator [ For Amplification, Sound Signals – 2025 ]
To convert dB to watts, subtract 30 from the dB value, divide by 10, and then raise 10 to the power of the result.
The DB ↔ Watts Calculator is exclusively designed to convert decibels (dB) to watts. Thus, it supports in the analysis of power levels in sound, signal strength, and audio systems.
This conversion is particularly beneficial for audio engineers, technicians, and those working with speakers or amplifiers to measure power in terms of watts. By comprehending this conversion, users can better manage sound intensity, power output, and equipment specifications.
Formula
W = 10^((dBm − 30) / 10)
Variable | Description |
---|---|
W | Power in watts |
dBm | Power level in decibels (dB) |
