Meaning of quecto-




Danilo Enrique Noreña Benítez

quecto-
  23

It is another prefix recently adopted by the International System, along with Quetta and Ronna for multiples and quecto and ronto for submultiples. They are represented as follows: Queta as Q, Ronna as R, Quecto as q and ronto as r. In this case that - means or indicates a factor of 10-30 (one quintillion th, on the Long Scale) and is used for submultiples or infinitely small parts. It is an the preceding 1 of 30 zeros. Quecto (symbol q) is a prefix adopted by Sistema Internacional in 2022. It is clarified that in the Short Scale used by Spanish-speaking countries the quecto would be called 1 Nonillonésimo (because our system uses 3 zeros less)

  




furoya

It is a prefix for a value raised to the thirtieth negative power, such as 10 8315;³ 8304; . It is taken from Greek 948; 949; 954; 945; ( deka "ten" ) , and this needs two explanations : first, the 10 is because it counts groups of thousandths, three zeros for decimals, and hence '30' because three zeros for decimal (0, 000) by 10 gives 1/1000¹ 8304; , or what is the same 0 , 000 82''000 82''000 82''000 82''000 82''000 82''000 82''000 82''000 82''001; and the name is modified to use a q as its symbol, which had no previous use that could be confused.
