A therm of natural gas sold to me for home use by Questar Gas cost 92 cents. The cost of a natural gas varies depending on what state you live in. Utah has the lowest cost of natural gas.
One therm equals 100,000 BTUs.
None. Gas is not measured in square metres.
BTU should be a measure of heating content, so it will vary with composition. However, in the US, 1 cubic ft of natural gas = 1,028 BTU. 1 therm = 100,000 BTU 100 cf = 0.1 Mcf approximately 1 therm (th). or more exactly 0.0972 Mcf = 1 th. See natural gas under wikipedia.

According to U.S. EPA, Inventory of U.S. Greenhouse Gas Emissions and Sinks: 1990-2004, 1 therm of natural gas burnt produces 11.7 lbs. of carbon dioxide emissions. Therefore, the Carbon Coefficient for natural gas is: 117 pounds of CO2 per million BTU, or 0.12 pounds per cubic foot of gas.
One therm equals 100,000 BTUs.
100 cubic feet equals 1 therm
You can not make natural gas.....it is NATURAL.

Sep - Oct 2011 bill reflected BGE Natural Gas Commodity at .5675 per therm & .5605. They were switching to winter rates.

I had already done the calculation for raising water from 60f to 125f using a cost of $1 per therm. This should give you a rough idea. Q=c*m*(t2-t1), where, c=specific heat of water (1 calorie/gram) m=mass of 1 gal of water = 3780 grams t is in degrees celsius: 60f-125f ==> 15.5C-51.6C Using those values, Q=[1 cal/gm][3780 gm/gal][51.6C-15.5C] ==>136458 cal/gal There are 25200 Kilicalories/therm, so 1364548 calories = .005 therm. So, at $1/therm for natural gas, the cost to heat 1 gallon of water from 60f to 125f is about 1/2 cent.
