Which prefix corresponds to 10^-9?

Explanation:
Think in powers of ten. SI prefixes attach to base units to show scale. 10^-9 means one part in a billion, which is the nano- prefix. We use nano- for very small quantities, like a nanometer (1 × 10^-9 meters) or a nanosecond (1 × 10^-9 seconds). It sits between micro- (10^-6) and pico- (10^-12) in size. For comparison, milli- is 10^-3, which is larger than nano-. So nano- is the prefix that corresponds to 10^-9.
