In addition to those listed in the everyday-use table, the SI includes standardised prefixes for 10 15 (peta), 10 18 (exa), 10 21 (zetta), 10 24 (yotta), 10 27 (ronna), and 10 30 (quetta); and for 10 −15 (femto), 10 −18 (atto), 10 −21 (zepto), 10 −24 (yocto), 10 −27 (ronto), and 10 −30 (quecto).

The prefixes from peta to quetta are based on the Ancient Greek or Ancient Latin numbers from 5 to 10, referring to the 5th through 10th powers of 10 3. The initial letter h has been removed from some of these stems and the initial letters z, y, r, and q have been added, ascending in reverse alphabetical order, to avoid confusion with other ...

2018年4月30日 · There are twenty prefixes. Ten prefixes increase the basic unit — gram or meter — by factors of 10: deca, hecto, kilo, mega, giga, tera, peta, exa, zeta, yotta. Ten more decrease the basic unit by factors of 10: deci, centi, milli, micro, nano, pico, femto, atto, zepto, yocto.

On the extremely large end of the spectrum, Peta (P) = 10 15, Exa (E) = 10 18, Zetta (Z) = 10 21, and Yotta (Y) = 10 24. Because the major prefixes in the metric system refer to powers of 10 that are multiples of 3 (from “kilo” on up, and from “milli” on down), metric notation differs from regular scientific notation in that the ...
