Comparison of Calorific Values, the following equations produce the same amount of heat:


1 cubic meter of natural gas = 9.8 degrees of electricity
1 cubic meter of natural gas = 14KG of steam
1 cubic meter of natural gas = 1.2KG of coal
1 cubic meter of natural gas = 0.96KG of heavy oil
1 cubic meter of natural gas = 0.94KG of diesel
1 cubic meter of natural gas = 0.88KG of liquefied petroleum gas
1 cubic meter of natural gas = 1.22KG of dimethyl ether



1 degree of electricity = 0.1 cubic meter of natural gas
1 degree of electricity = 1.4KG of steam
1 degree of electricity = 0.12KG of coal
1 degree of electricity = 0.1KG of heavy oil
1 degree of electricity = 0.09KG of diesel
1 degree of electricity = 0.09KG of liquefied petroleum gas
1 degree of electricity = 0.12KG of dimethyl ether



1KG of steam = 0.698 degrees of electricity


1KG of steam = 0.071 cubic meter of natural gas
