Etymology of YOCTO-

The prefix "yocto-" is derived from the Latin term "octo", which means "eight". It is based on the International System of Units (SI) prefixes, which represent multiples and fractions of units. In this case, "yocto-" denotes one quintillionth (10^-24) of a unit.

The creation of "yocto-" as an SI prefix was proposed in 1990 by physicist Thomas A. Walsh, who derived the term from the Latin word "octo" and combined it with the SI prefix "yotta-" (10^24), creating the contrast between the largest and smallest SI prefixes. The proposal was accepted by the International Bureau of Weights and Measures (BIPM) in 1991 and officially included in the SI system in 1995.
