This calculator is used to convert from dB to Watt as a measure of sound or noise level.
📢 Note: This is an audio sound power level calculator
🛜 If instead you’re looking to convert a dBm (deciBel relative to 1 mW) Radio Frequency Power value to Watt, use this calculator instead.
Sound power levels or LwdB are determined by the following formula:
LwdB = 10*Log10 (Lw/ LR)
The reference power LR is one trillionth of a Watt or 10-12 W
Use the tool below to convert from dB to Watt
The picture below shows the sound power level in dB vs the sound power level in Watt (W)
