Picowatt per square meter (pW/m²): One trillionth of a watt per square meter. The reference sound intensity is 1 pW/m².

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).

How to convert picowatts per square meter to decibels IL

To convert picowatts per square meter to decibels IL, take the base-10 logarithm of the amount, then multiply by 10.

Formula

dB IL = 10 × log₁₀(pW/m²)

Examples

  • 1 pW/m² = 10 × log₁₀(1) = 0 dB IL
  • 1000000 pW/m² = 10 × log₁₀(1000000) = 60 dB IL
  • 1e12 pW/m² = 10 × log₁₀(1e12) = 120 dB IL
