How to convert Millimeters to Light Years
Multiply the millimeters value by 1.057e-19: 1 mm = 1.057e-19 ly. Going the other way, 1 ly = 9.461e+18 mm, so divide by 1.057e-19 or use the Light Years to Millimeters converter.
About these units
Millimeters (mm)
A millimeter is one thousandth of a meter. It is the usual unit for engineering drawings, paper sizes and anything measured finer than a centimeter.
Light Years (ly)
A light-year is the distance light travels through a vacuum in one Julian year, about 9.461 trillion kilometers. Despite the name it measures distance, not time, and is used for stars and galaxies.
