What does the prefix nano represent?

Explanation:
Nano represents 10^-9, one billionth of a unit. It’s used for very small quantities, so a nanometer is 10^-9 meters and a nanosecond is 10^-9 seconds. For example, 7 nm equals 7 × 10^-9 meters. Conversely, 1 meter equals 10^9 nanometers. This prefix sits between micro (10^-6) and pico (10^-12), and it helps you gauge how tiny things at the nanoscale are.
