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 millimeter (mm) belongs to the metric (SI) and is typically found in measurements related to engineering and manufacturing tolerances and bolt and screw dimensions. By definition, one light-year is the distance light travels in one Julian year in a vacuum, approximately 9.461 × 10¹⁵ meters. One millimeter is one thousandth of a meter (0.001 m). The conversion factor between these two units is 9460700000000000000: multiplying any value in ly by this number gives the equivalent in mm. For example, 10 ly equals 94607000000000000000.0000 mm. Going the other direction, 1 mm equals 0 ly.
