MMBTU â One million British Thermal Units or BTUs. Natural gas is generally bought and sold in MMBTUs and future prices are generally quoted in this unit of measure. Therm â 1 Therm = 100,000 BTUs. SCF â Standard Cubic Foot is one cubic foot of gas at standard temperature and pressure (60 degrees F and sea level).
One cubic foot of natural gas would fit in a cube, 12 inches square and 12 inches high. For more convenient billing, we measure and price gas in units of 100 cubic feet or CCF which is the unit of measure you will see on your natural gas bill.f a customer uses 5000 cubic feet of natural gas in a billing period, they would actually see their usage as 50 CCF on their bill. This corresponds with the rate tariff which will show the appropriate charge per CCF used.
