How the Calculation Works (Linear Scaling)
Formula:
Bel = Decibel / 10
Substitution:1 / 10
Calculated Result:0.1 B
Since 1 Bel = 10 Decibels, divide the value in Decibels by 10.
Standard Ratio Factor:1 dB = 0.1 B

📌 Standard Benchmark Reference Values
10 dB=1 B (bel)
Standard tenfold logarithmic power ratio definition (1 B = 10 dB).
Exact RatioDecibel (dB)
One tenth of a bel (1 dB = 0.1 B). In acoustic measurements, sound level L (dB) = 10 log₁₀(P/P₀) = 20 log₁₀(p/p₀) for root-power quantities.
Bel (B)
A dimensionless logarithmic level ratio unit defined as the base-10 logarithm of a power ratio (L = log₁₀(P/P₀)). In sound level measurement, 1 bel represents a tenfold change in power ratio.
