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).
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.
