- Speed of light [r]: A physical constant c describing the speed of electromagnetic radiation in vacuum. In the International System of Units the metre is the distance light travels in classical vacuum in 1/c seconds, using the defined value c = c0 ≡ 299 792 458 m/s (exact). [e]
- Light year [r]: Distance that light travels in vacuum in one year; 9,460,730,472,580.800 km = 9.4607304 * 1012 km. [e]
- Light day [r]: Distance that light travels in a vacuum in one day; 1 light day = 25,902,068,371,200 m = 2.5902067 * 1013m. [e]
- Light minute [r]: Distance that light travels in vacuum in one minute; 17,987,547,480 m = 1.7987547 * 1010m. [e]
- Light second [r]: Distance that light travels in vacuum in one second; 2.99792458 * 108m. [e]
