What is the relationship between the high school Carnegie Unit and a College Credit?

"How Do College Courses Earn Me High School Credit?

From the ODE Website: "College Credit Plus allows high school students to earn college credit and apply that credit toward their high school graduation requirements. Successful completion of a three or more credit-hour college course will result in 1.0 Carnegie unit earned at the high school. A two credit-hour college course will earn students 2/3 of a high school credit and a one credit-hour college course will convert to 1/3 of a high school credit" (Source: www.ohiohighered.org/ccp)
