About Light-year (ly)

The distance light travels in one Julian year -- approximately 9.461 trillion kilometers -- the light-year is the standard unit for expressing interstellar distances. Proxima Centauri, the nearest star beyond the Sun, lies about 4.24 light-years away. Despite its name, the light-year measures distance, not time.

About Millimeter (mm)

At one thousandth of a meter, the millimeter provides the precision needed in mechanical engineering, machining tolerances, and rainfall measurement. Bolts, bearings, and smartphone thickness are all specified in millimeters, and weather stations report precipitation depth in mm accumulated over a given period.
