1 therm of UK gas is approximately equal to 29.3 kilowatt-hours. The price of 1 therm can vary depending on the provider and market conditions, but it is typically around £0.035 to £0.04.
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 hundred cubic feet (ccf) of natural gas is approximately equal to 1.037 therms. This conversion can vary slightly depending on the specific energy content of the gas, but 1 ccf generally translates to about 1 therm for practical purposes.
1 UK cup = about 8.45 UK fluid ounces.
Prices on both commodities depend on the market for which they are most closely associated with as well as the time of year ("season"). A gallon (Methane converted from MMBTu unit of measure to Gallon) to gallon comparison of Methane ("Natural Gas") to Propane currently tracks close, in some markets, Methane yeilding just under a dollar & propane above a dollar. (Note: prices are always subject to market conditions; supply, demand, associated expenses to take the product to market.)
1 therm of gas is equal to 100,000 BTUs (British Thermal Units).
100 cubic feet equals 1 therm
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.
1 Therm is 100,000 BTU, and as there are 1000 BTU in 1 cubic foot of gas, 1 Therm = 100 cubic feet. Density of methane = 0.72 kg/cubic meter which is 35.3 cubic feet, so 100 cubic feet = 2.04 kg
1 Therm is equal to 100,000 BTU.
There are 1 therm in every 1 ccf of natural gas. Therefore, 100 ccf of natural gas is equal to 100 therms.
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.
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.
A good rate for natural gas is typically around 1 to 2 per therm, depending on factors such as location, market conditions, and supplier.
A BTU is the amount of heat required to raise the temperature of 1 pound (0.454 kg) of liquid water by 1 °F (0.56 °C)therefore = to about 1055 joules.
I was just researching this same question today. Here's what I found hope it helps. 1 Therm = 100,000 BTU 10 Therms = 1MMBTU ( Million BTU's ) Therefore to convert from MMBTU to Therms, multiply the MMBTU figure by 10 to get Therms. Note: Therm to BTU conversion is based on the amount of energy obtained from burning 1 Therm (100 cubic feet of natural gas). This value is not exact, but close, and could be different from one natural gas field to another.
