Glossary » Units » Logarithm of a Ratio » Neper
Neper (NP) is a unit in the category of Logarithm of a ratio. It is also known as nepers. Neper (NP) 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 4.342944819.
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 (power) (dB (power)), and Decibel (voltage) (dB (voltage)).
