There's approximately 91,500 btu's in a gallon of propane. Using as an example, a 12 cu/ft Norcold refrigerator that burns 2400 btu/hr.
One gallon of propane will last about 38 hrs. if the refrigerator runs constantly.
Apparently the math portion of this calculation was lost.
If a gallon of propane will run the fridge 24/7 for 38 hours, and a 20 pound tank holds 4.7 gallons, a 20 pound tank would then run that 12 cu. ft. fridge for (38 X 4.7) 178.6 hours.
That is 7.44 days of the burner running 24/7, that is in EXCESS of one week.
So unless one has a larger than 12 cu. ft. unit, it is theoretically impossible for a fridge to burn through a 20 pound tank in a week, even if it ran non-stop for the whole week.
