   25 mar 2020 · The speed of light is defined to be 299,792,458 metres per second - because in the SI system the metre is defined to be the distance light travels in 1/299792458 of a second. A mile is nowadays defined to be 1,609.344 metres, and an hour is just 3600 seconds, so that's 670,616,629 mph.
