bel to decibel
Please provide values below to convert bel [B] to decibel [dB], or change ↔.
bel [B]
Definition: The bel (B) is a unit used to express ratios of power, sound intensity, or voltage in a logarithmic scale, primarily used in acoustics and telecommunications.
Historyandorigin: The bel was named in honor of Alexander Graham Bell, the inventor of the telephone. It was first introduced by the Western Electric Company in the 1920s for telecommunications purposes.
CurrentUse: Although the bel is seldom used today, its subunit, the decibel (dB), is extensively used in telecommunications, audio, acoustics, and electronics to measure power ratios and sound intensities.
funfact: Named after Alexander Graham Bell, the bel is rarely used in isolation, with the decibel (dB) being a more commonly used subunit.
decibel [dB]
Definition: The decibel (dB) is a logarithmic unit used to measure sound intensity, power levels, and signal strength, representing a tenth of a bel.
Historyandorigin: The decibel was introduced in the 1920s as a way to quantify sound intensity and other related parameters, being one-tenth of a bel. It was adopted for its convenience in representing large variations in signal strength or sound intensity.
CurrentUse: The decibel is used globally in many fields including audio engineering, acoustics, telecommunications, and electrical engineering, to measure sound levels, signal strength, and power ratios.
funfact: Decibels are widely used in various fields, such as acoustics, electronics, and telecommunications, due to their ability to express large ranges of values in compact form.

How to Convert bel to decibel
1 bel [B] = 10 decibel [dB]
1 decibel [dB] = 0.1 bel [B]
we use cross multiplication method
bel [B] → decibel [dB]
1 → 10
1.5 → ?( suppose x)
=>1.5*10=1*x
by simplifying
x=15
