What does prefix nano- mean?
really small. Divided into a billion parts. A nanometer is one
billionth of a meter. A nanosecond is one billionth of a second. A
nanocraig would be one billionth of some guy named Craig.Ex. if you
have 650 nm it would be equivalent to 650 x10^-9 m

What does the SI prefix 'nano' mean?
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.
