Hydrogen
hydrogen calorific value is 150000 kJ/kg
Carbohydrates
Blast furnace calorific value is 780 Kcal/hr
The water gas has a high calorific value because it produces immense heat during its combustion.
Anthracite has the highest calorific value. and South African coal is best in the world.

calorific value of producer gas is 05 MJ m− 3 Reference http://www.kayelaby.npl.co.uk/chemistry/3_11/3_11_4.html Thanks
The calorific value of petrol/gasoline (and also its gas but it might be slightly different) is apprx. 50 kilojoules/gram of complete combustion.
The calorific value of LPG (liquefied petroleum gas) is approximately 46,000 kilocalories per kilogram.

To convert kilowatt-hours (kWh) to cubic meters (m³) of natural gas, you need to know the calorific value of the gas, which is typically around 9.5 to 11 kWh per cubic meter, depending on the gas composition. The conversion can be done using the formula: m³ of gas = kWh / calorific value (kWh/m³). For example, if the calorific value is 10 kWh/m³, then 100 kWh would equal 10 m³ of natural gas. Always check the specific calorific value for more accurate conversions.
