The light-second is a unit of length useful in astronomy, telecommunications and relativistic physics. It is defined as the distance that light travels in free space in one second, and is equal to exactly 2997 ..more definition+
The Hectometer (symbol: hm), or hectometre (International spelling) is an uncommonly used unit of length in the metric system, equal to one hundred meters. It derives from the Greek word "ekato", meaning "hundre ..more definition+
