The prefix nano- is equal to 10-9 and is represented by the Greek letter nu, which looks like a lower-case v. But when writing it on tests and papers, just use a lower-case n, so nanoseconds, for example, is abbreviated nsec or ns.
It basically means "one billionth." So a nanosecond is one billionth of a second.
'Nano' is not a noun; 'nano' is not even a word, it is a prefix meaning 'one billionth' or used informally as an extremely small part of a whole. Some words with the prefix nano- are nanosecond, nanotechnology, or nanoscale.
The SI prefix deci- means one-tenth (1/10) or 0.1. It is used to denote a factor of 10^-1 in the International System of Units.
The SI prefix "deca-" represents a multiple of ten.
"Micro micro" was an older designation used for a metric prefix that is now known as the prefix "pico," which represents one trillionth (1/1,000,000,000,000). The use of "micro micro" was eventually replaced by the standardized SI prefixes to avoid confusion.
The fraction prefix that means one trillionth is nano-.
The SI nano- prefix means x 10-9
