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 ..more definition+
The picometer (symbol: pm) or picometre (International spelling) is a unit of length in the metric system, equal to 1×10−12 m, or one trillionth (1/1000000000 ..more definition+
