**Decibel (power)**

**Decibel (power) (dB (power))**is a unit in the category of

*Logarithm of a ratio*. It is also known as decibels. This unit is commonly used in the SI unit system. Decibel (power) (dB (power)) has a dimension of nil (log) where L is length, N is amount of substance, and I is electric current. It essentially the same as the corresponding standard SI unit dB.

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 (power) (B (power)), Bel (voltage) (B (voltage)), Decibel (voltage) (dB (voltage)), and Neper (N_{P}).
