Zetta- (symbol Z) is a prefix in the metric system denoting a factor of 1021 or 1000000000000000000000. i like dogs dogs are cool i got two Added to the SI in 1991, it is derived from the French prefix septo, meaning seven, because it is equal to 10007.[1]

A prefix of the same value, hepta, was informally introduced a few years before the promulgation of zetta. It was formed from the Greek ἑπτά, (hepta), also meaning seven. Hepta never received official sanction and is now obsolete.

Notes
  1. ^ Prefixes adopted before 1960 already existed before SI. The introduction of the CGS system was in 1873.
