about 1,000 BTU/ft3. See related link. It is not exact because natural gas composition varies. A richer gas would have a higher heating value. The cubic feet (ft3) is often abbreviated scf, or standard cubic feet, measured at 60 deg F and 14.7 psia. Future market gas prices at quoted in $/mmBTU or dollars per million BTU (currently around $4/mmBTU), equivalent to $4.00/Mscf. See related site.
For the purpose of gas rating 1040 btu's/ft3
Natural gas burns hotter than oil. Natural gas has a higher heating value per unit volume compared to oil, making it a more efficient and hotter-burning fuel.
On average, about 1050 cubic feet of natural gas is required to produce 1 ton of steam. This can vary depending on the efficiency of the boiler and the heating value of the natural gas being used.
There are many reason why natural gas is usually a cheaper option for heating when compared to heating with electricity. The biggest reason is heating with therms is cheaper than kilowatts.
Natural gas is a cleaner-burning fossil fuel compared to coal and oil, resulting in lower greenhouse gas emissions. It is a versatile energy source used for electricity generation, heating, cooking, and transportation. Natural gas is abundant and relatively affordable, contributing to energy security and economic stability.
Natural gas comes out of the ground. As a product of nature, natural gas is not the same from country to country. Methane is the main component, but metane's percentage can vary between 80% and 95%. Others hydrocarbons' percentage (for example ethane, propane, butane etc) also vary. Since heating value depends on the percentage of the hydrocarbons, heating value also varies.
Natural gasses are a by-product of oil production. Where you will find oil, you will have natural gas. Commercially, natural gasses are used for heating, cooking, and producing of electricity.
It will vary somewhat with the composition of the natural gas, but roughly 133 cubic ft of natural gas has the same heat value as 1 gallon of #2 heating oil. Minutes do not enter into the calculation
gas is converted into electricty, than that is used for heating.
Oil central heating tends to be more expensive when compared to gas central heating as the price for heating oil tends to be higher when compared to natural gas. The price of heating oil also tends to be more volatile than natural gas.

The net heating value will considering the evaporation of water formed in reaction of natural gas decomposition as follow CnHm+(n+m/4)O2=nO2+m/2H2O For Methane : CH4 we have n=1 " number of carbon m=4 " number of hydrogen then: CH4+(1+4/2)O2 O2+2H2O=CH4+3O2=2H2O Subtracting enthalpy of products from reactants to get enthalpy of decomposition
Natural gas - used for heating, cooking etc.

The original source of energy for this heating system is electricity or natural gas. Electric heating systems convert electrical energy into heat, while gas heating systems burn natural gas to produce heat.
