The nanometer is a unit of length equal to one-billionth of a meter (0.000000001 m). It's commonly used in scientific research, particularly in fields such as physics, chemistry, and biology, where extremely small scales are relevant.
An astronomical unit (AU) is a unit of length used in astronomy, representing the average distance between the Earth and the Sun, approximately 149.6 million kilometers (about 93 million miles).
