Natural Gas is sold to customers in units of 100 cubic feet (Therm). One Therm represents approx. 100,000 BTU of heating power, enough to heat a normal home for about two hours during colder weather.
MCF is ten Therms, or one million BYUs. Prices for CNG can vary, from as low as $0.80 to as high as $1.00 per Therm.
Natural Gas is delivered to the customer at home at very low pressure, usually less than 1/2 to 3 PSI (pounds per square inch).
Q- How many cubic feet of gas does it take to make 1 GGE (Gas Gallon Equivalent) of CNG?
A- 120 cubic feet = 1 GGE estimate
Q- How much does 1 GGE of natural gas weigh?
A- 5.5 lbs.
The average heat value of natural gas id 1080 BTU per cubic foot and burn at roughly 117 - 125 octane with an ignition temperature of 1080 degrees.
1 Therm = 100 cubic foot @ 100,000 BTU
1 GGE = 1.14 - 1.25 Therms
1 Gallon = 3.75 liters
20 Gallons = 75 liters
40 Gallons = 150 liters
1 Barrel of Oil = 300 lbs of oil
