What is the prefix for 10^-9?

Explanation:
In the metric system, prefixes map to powers of ten. The prefix nano means one billionth, which is 10^-9. So a nanometer is one billionth of a meter, a nanosecond is one billionth of a second, and so on. The other prefixes shown correspond to different powers: milli is 10^-3, kilo is 10^3, and giga is 10^9. Therefore, nano is the correct prefix for 10^-9.
