**Part Per Quadrillion**

**Part Per Quadrillion (ppq)**is a unit in the category of

*Fraction*. It is also known as parts per quadrillion. This unit is commonly used in the INT unit system. Part Per Quadrillion (ppq) has a dimension of nil (fraction) where L is length, T is time, N is amount of substance, and I is electric current. It can be converted to the corresponding standard SI unit by multiplying its value by a factor of 1E-015.

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 Fraction include Carat (karat) (ct, Kt), Part Per Billion (ppb), Part Per Hundred (pph, %), Part Per Hundred Million (pphm), Part Per Hundred Thousand (ppht), Part Per Million (ppm), Part Per Tera (ppt), and Part Per Thousand (ppt).
