Quick Answer. Natural gas is measured in cubic feet, cubic meters, British thermal units or joules, while gasoline is measured in gallons, British thermal units, joules or metric tons. The unit used to measure gas is dependent upon the situation in which the gas is being used.
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.
