**Bel (power)**

**Bel (power) (B (power))**is a unit in the category of

*Logarithm of a ratio*. It is also known as bels. Bel (power) (B (power)) has a dimension of nil (log) where L is length, N is amount of substance, and I is electric current. It can be converted to the corresponding standard SI unit dB by multiplying its value by a factor of 10.

Note that the seven base dimensions are M (Mass), L (Length), T (Time), Q (Temperature), N (Aamount of Substance), I (Electric Current), and J (Luminous Intensity).

Other units in the category of Logarithm of a ratio include Bel (voltage) (B (voltage)), Decibel (power) (dB (power)), Decibel (voltage) (dB (voltage)), and Neper (N_{P}).
