Contact/Outside Work/Credit Hour Ratio
UNC schools, like most institutions of higher education, use the Carnegie Unit to measure credit hours. Very roughly generalized, the unit indicates that students earn one credit for 150 minutes of class work and individual work per week for 15 weeks. That means 150 minutes of lab time, 50 minutes of lecture/discussion plus 100 minutes of outside work, 150 minutes of ensemble, field trip, practicum, studio etc. (For purposes of clarity, I fall back in part to hours here, rather than 50 mins. We will have to minutes, ultimately.)
This plays out in different ways:
I. Lecture (seminar, discussion, recitation) (1credit= 1 contact hour +2 hours homework)
A one credit-hour course meets for fifteen 50-minute sessions of classroom instruction (or equivalent) with two hours of outside study for each class session. A 3 credit-hour course meets three 50-minute sessions or two 75 minute sessions per week for fifteen weeks, with six hours outside work per week.
II. Self-Containted Laboratory Activity supervised as a group (ensemble, studio, laboratory, field trip, practicum, workshop, group studio) (1 credit =3 hours lab time + no extra work) Non-self contained labs have less lab time and more outside expectation, to varying degrees.
One credit hour earned for the equivalent of fifteen 150-minute periods of such activity, with little or no outside preparation expected. Forty-five 150-minute sessions would earn three credits
Lecture/lab combinations also exist, with various distributions of Contact time and outside work.
At its discretion, an institution may award credit hours for learning acquired outside the institution which is an integral part of a program of study. When life or work experience is to be credited as a concurrent portion of an academic program design, as in an internship, one semester credit hour will be awarded for each 40-45 clock-hour week of supervised academic activity that provides the learning considered necessary to program study.
Credit hours may be earned in short sessions (block study, summer sessions, intersessions, etc.) proportionately to those earned for the same activity during a regular term of the institution, normally at no more than one credit per week of full-time study.

I quote the below regulation from UNC-CH registrar, but you can find the exact text on university sites around the country.
FEDERAL DEFINITION OF A CREDIT HOURFrom our Trimester to Semester Conversion Guide:
"Credit Hour Minimum for 4-year program is120 and 140 hours "
Combined with the above regulation, this translates to workload like this: 15hrs. per term= 45 hours per week/15 weeks and 140 hours 17.5 hours per term= 52.5 hours per week/15 weeks. These maximums protect students, faculty, and budget from overwork.
SEMESTER Credit Hour Calculations -- SoF
LECTURE = 750 minutes per semester per credit
1 cr = 750 min./semester = 15 hours = 1 hr/wk of class
2 cr = 1,500 min./semester = 30 hours = 2 hrs/wk of class
3 cr = 2,250 min./semester = 45 hours = 3 hrs/wk of class
LECTURE/LAB “1⁄2and 1⁄2” classes
4 hrs/wk: 1⁄2 and 1⁄2 Lecture/Lab = 3 cr
50 min. x 4 hrs/wk = 200 min/wk x 15 wks = 3,000 min./sem.
3,000 divided by 2 = 1,500 (half for Lecture, half for Lab minutes)
1,500 div. by 1,500 = 1 Lab credit
1,500 div. by 750 = 2 Lecture credits
3 hrs/wk: 1⁄2 and 1⁄2 Lecture/Lab = 2 cr
50 min. x 3 hrs/wk = 150 min/wk x 15 wks = 2,250 min./sem
2,250 div. by 2 = 1,125 (half for Lecture, half for Lab minutes)
1,125 div. by 1,500 = .75 Lab credit
1,125 div. by 750 = 1.5 Lecture credit
21⁄2 hrs/wk: 1⁄2 and 1⁄2 Lecture/Lab = 2 cr
50 min. x 2.5 hrs/wk = 125 min/wk x 15 wks = 1,875 min./sem
1,875 div. by 2 = 937.5 (half for Lecture, half for Lab minutes)
937.5 div. by 1,500 = .625 Lab credit
937.5 div. by 750 = 1.25 Lecture credit
Total = 1.875 which rounds up to 2 credits
LAB = 1,500 minutes per semester per credit
6 credits = 9,000 min/sem (div. by 50 min. = 180 hours /sem div. by 15 wk = 12 hrs/wk)
4 credits = 6,000 min/sem (div. by 50 min. = 120 hours /sem div. by 15 wk = 8 hrs/wk)
3 credits = 4,500 min/sem (div. by 50 min. = 90 hours /sem div. by 15 wk = 6 hrs/wk)
2 credits = 3,000 min/sem (div. by 50 min. = 60 hours /sem div. by 15 wk = 4 hrs/wk)
1 credit = 1,500 min/sem (div. by 50 min. = 30 hours/sem div. by 15 wk = 2 hrs/wk)
