How the Calculation Works (Linear Scaling)
Formula:
Bel = Neper / 1.151293
Substitution:1 / 1.151293
Calculated Result:0.8686 B
Since 1 Bel = 1.151293 Nepers, divide the value in Nepers by 1.151293.
Standard Ratio Factor:1 Np = 0.868589 B

Neper (Np)
A logarithmic level ratio unit based on natural logarithms (base e). Under the international amplitude/field ratio convention (ISO 80000-3), 1 Np = ln(e) = 2 / ln(10) B ≈ 0.8685889638 B ≈ 8.685889638 dB.
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.
