About this conversion

The millimeter (mm) is a unit of length in the metric (SI), commonly used for engineering and manufacturing tolerances and bolt and screw dimensions. The light-year (ly) belongs to the astronomical and is typically found in measurements related to distances to nearby stars and sizes of galaxies. By definition, one millimeter is one thousandth of a meter (0.001 m). One light-year is the distance light travels in one Julian year in a vacuum, approximately 9.461 × 10¹⁵ meters. The conversion factor between these two units is 1.0570042385869967e-19: multiplying any value in mm by this number gives the equivalent in ly. For example, 10 mm equals 0.0000 ly. Going the other direction, 1 ly equals 9460700000000000000 mm.
