The CH Scale refers to the Cute-Hot Scale. Each factor in the scale is rated on a 1-10 scale, for example a girl can have a cute factor of 7 and a hot factor of 10. Characteristics that are involved in judging the CH Scale are looks, personality, life goals, etc. Created by the 2010-2011 residents of 17th floor of Straz Tower at Marquette University.
