Is it true that is a credit hour the same as a semester hour based on the following text?

In a college or university in the United States, students generally receive credit hours based on the number of ''contact hours'' per week in class, for one term; more well known as Semester Credit Hours. A contact hour includes any lecture or lab time when the professor is teaching the student or coaching the student while they apply the course information to an activity. Regardless of the duration of the course (i.e. a short semester like summer or intersession) and depending on the state or jurisdiction, a semester credit hour (SCH) is 15-16 contact hours per semester. Most college and university courses are 3 Semester Credit Hours (SCH) or 45-48 contact hours, so they usually meet for three hours per week over a 15-week semester.
