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.
A parsec (pc) is a unit of length used in astronomy, representing the distance at which one astronomical unit subtends an angle of one arcsecond, approximately 3.086 trillion kilometers (about 3.262 light years).
