Decibel IL (re 1 pW/m²) (dB IL): Sound intensity level: 10 times the base-10 logarithm of the sound intensity divided by the reference intensity of 1 pW/m² (10⁻¹² W/m²).
Picowatt per square meter (pW/m²): One trillionth of a watt per square meter. The reference sound intensity is 1 pW/m².

How to convert decibels IL to picowatts per square meter
To convert decibels IL to picowatts per square meter, divide the level by 10, raise 10 to that power.
Formula
pW/m² = 10^(dB IL ÷ 10)
Examples
- 0 dB IL = 10^(0 ÷ 10) = 1 pW/m²
- 60 dB IL = 10^(60 ÷ 10) = 1000000 pW/m²
- 120 dB IL = 10^(120 ÷ 10) = 1000000000000 pW/m²
