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).
Watt per square meter (W/m²): SI unit of heat flux density and irradiance. Full sunlight at ground level is roughly 1000 W/m².

How to convert decibels IL to watts per square meter
To convert decibels IL to watts per square meter, divide the level by 10, raise 10 to that power, then multiply by 1e-12.
Formula
W/m² = 1e-12 × 10^(dB IL ÷ 10)
Examples
- 0 dB IL = 1e-12 × 10^(0 ÷ 10) = 1e-12 W/m²
- 60 dB IL = 1e-12 × 10^(60 ÷ 10) = 0.000001 W/m²
- 120 dB IL = 1e-12 × 10^(120 ÷ 10) = 1 W/m²
