Conversion Formula
pc = nm × 3.240779289e-26
About Nanometers
A nanometer (nm) is one billionth of a meter (10⁻⁹ m), roughly the width of 3-4 atoms placed side by side. This scale is where nanotechnology operates and is visible light wavelengths are measured. Visible light ranges from about 400 nm (violet) to 700 nm (red). DNA molecules are about 2.5 nm wide, and modern computer processors have transistors as small as 3-5 nm. A human hair is approximately 80,000-100,000 nanometers thick, making one nanometer incredibly tiny by human standards.
About Parsecs
A parsec (pc) is approximately 3.26 light years or 30.86 trillion kilometers, defined as the distance at which one astronomical unit subtends an angle of one arcsecond. Despite being less familiar than light years, parsecs are preferred by professional astronomers because they relate directly to stellar parallax measurements - the apparent shift in a star's position as Earth orbits the Sun. Most nearby stars are within a few dozen parsecs, our galaxy is about 30,000 parsecs across, and distant galaxies are measured in millions of parsecs (megaparsecs).
