This tool converts deciBel (**dB**) to **W/m ^{2}** (W/m^2).

Enter the dB value and the tool will provide the equivalent value in W/m^{2}

**Formula**

**I = Io *10 ^{(IdB/10)}**

where

**Io**= 1×10^{-12}W/m^{2}is the reference power**I**is the deciBel value_{dB}**I**is the power measurement in W/m²

Io is the lowest sound intensity that a person with normal hearing can perceive at a frequency of 1000 Hz

**Example Calculation**

**20 dB**converts to**1×10**^{-10}W/m^{2}**10 dB**converts to**10 pW/m**^{2}
