SIU Carbondale has used a semester hour system since Fall 1974 (More information about semester credit hours is here). From 1930 through Summer 1974, a quarter hour system was in use.  (One quarter hour is equivalent to ⅔ of a semester hour, while one semester hour is equivalent to 1½ quarter hours.)
