Nanometers (nm) to Light-years (ly) Conversion
Nanometers
The nanometre is a unit of length equal to one billionth of a metre (10⁻⁹ m) and represents the fundamental scale of atomic and molecular structures. The diameter of a hydrogen atom is approximately 0.1 nm, a DNA double helix is about 2 nm wide, and a typical protein ranges from 1 to 100 nm. The nanometre is the primary unit in nanotechnology, materials science, and optics: the wavelength of visible light spans roughly 380–700 nm.
Light-years
The light-year is a unit of astronomical distance equal to the distance that light travels in a vacuum in one Julian year (365.25 days), approximately 9.461 × 10¹⁵ metres. Despite containing the word "year," it is strictly a unit of distance, not time. The nearest star system, Alpha Centauri, is approximately 4.37 light-years away, while the observable universe extends approximately 46 billion light-years in every direction.
