Unit prefix The prefix "bronto", as used in the term "brontobyte", has been used to represent anything from 10 to 10 bytes, most often 10. The SI includes standardised prefixes for 10 (peta), 10 (exa), 10 (zetta) and 10 (yotta). In 2010, an online petition sought to establish hella as the SI prefix for 10, a movement that began on the campus of UC Davis. The prefix, which has since appeared in the San Francisco Chronicle, Daily Telegraph, "Wired" and some other scientific magazines, was recognised by Google, in a non-serious fashion, in May 2010.
