What does the prefix 'nano' represent in scientific notation?

The prefix 'nano' in scientific notation represents a factor of (10^{-9}). This means that when you see 'nano' as a prefix in science or technology, it indicates that the value is one billionth of the base unit. For example, a nanometer is (10^{-9}) meters, which is a very small measurement commonly used in fields like physics and biology to describe dimensions at the atomic and molecular scale. Understanding this prefix is crucial in conversions and calculations involving measurements on a very small scale, thereby allowing for precise communication of scientific data.
