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.
Most modern gas meters measure gas in cubic metres (m 3). The energy contained in gas is measured in kilowatt-hours (abbreviated to kWh) and for natural gas is 11.2 kWh per cubic metre. Older gas meters measure gas in hundreds of cubic feet - 100 cubic feet equal 2.83 cubic metres.ost modern gas meters measure gas in cubic metres (m 3).
