- ***************************************************************************
- *
- * Description: This file is based on the SystemOfUnits provided
- * in the CLHEP library v1.2: The units remain the same.
- * It is just the naming conventions that are different:
- *
- * 1) No single letter unit:
- * : m --> meter
- * : s --> second
- * : g --> gram
- *
- * 2) All prefixes are spelled out explicitly (except electron Volt):
- * : ns --> nanosecond
- * : mm --> millimeter
- *
- * 3) All units with proper names follow the international standard
- * of being lower case:
- * : farad --> farad
- * : volt --> volt
- *
- * The basic units are :
- * centimeter (centimeter)
- * second (second)
- * Giga electron Volt (GeV)
- * positron charge (eplus)
- * degree Kelvin (kelvin)
- * the amount of substance (mole)
- * radian (radian)
- * steradian (steradian)
