About this conversion
The light-year (ly) is a unit of length in the astronomical, commonly used for distances to nearby stars and sizes of galaxies. The nanometer (nm) belongs to the metric (SI) and is typically found in measurements related to visible light wavelengths (400–700 nm) and chip transistor node sizes. By definition, one light-year is the distance light travels in one Julian year in a vacuum, approximately 9.461 × 10¹⁵ meters. One nanometer is one billionth of a meter (10⁻⁹ m). The conversion factor between these two units is 9.460699999999999e+24: multiplying any value in ly by this number gives the equivalent in nm. For example, 10 ly equals 9.4607e+25 nm. Going the other direction, 1 nm equals 0 ly.
