Yokto	y	10^-24	Quadrillionstel
Ronto	r	10^-27	Quadrilliardstel

Please notice the following inconsistencies:

Values smaller than 1 have a lowercase character and multiples have a highercase character. There are 3 exception here: Deka (da), Hekto (h) and Kilo (k). This is historical.

The high values end on "a" the low values end on "o".

Have fun.
