About These Units
Light Year (ly)
A light year (ly) is the distance light travels in one year: approximately 9.461 trillion kilometers or 5.879 trillion miles. Light years measure interstellar distances. The nearest star Proxima Centauri is 4.24 light years away. Light travels 299,792 km/second.
Picometer (pm)
A picometer (pm) is a metric unit equal to one trillionth of a meter or 0.001 nanometers. Picometers measure atomic radii (30-300 pm), chemical bond lengths, and X-ray wavelengths. Used primarily in chemistry, physics, and crystallography.
