40 //
41 // This class maintains a table of Units.
42 // A Unit has a name, a symbol, a value and belong to a category (i.e. its
43 // dimensional definition): Length, Time, Energy, etc...
44 // The Units are grouped by category. The TableOfUnits is a list of categories.
45 // The class G4BestUnit allows to convert automaticaly a physical quantity
46 // from its internal value into the most appropriate Unit of the same category.
