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 millimeter (symbol = mm), or millimetre (British spelling) is a unit of length in the metric system, equal to one thousandth of a meter, which is the SI base unit ..more definition+
