There are multiple methods of determining the heating value of fuels dependant upon the compounds present. Generally either the constituents and quantities of the compounds in the fuel are determined and the known heating value of each compound is used to determine heating value of the fuel; or a total calorific measurement can be made.
"What is the density of fuel oil?"
Oil heating is a form of fuel which is an alternative to electric powered heating. More information about oil heating can be found online on Wikipedia.
The oil heating industry sells residential fuel oil to houses that use oil tanks for heating purposes. Fuel oil distributors are contacted when a household's oil supply is low. A fuel oil delivery is then scheduled and a truck will come to refill the tank on the scheduled date. The price of residential heating oil largely fluctuate based on your location, current demand, and speculation. Emergency heating oil delivery can also be scheduled.

The heating value of fuel oil varies depending on the grade. For residential heating, FO2 produces 137 to 141.8 thousand BTU per gallon. Propane has a heating value of 23.811 thousand BTU per lb. or 91k per gallon. This means 3.01 to 3.12 gallons are needed.
The residential heating oil industry is currently working to cut the sulfur content of heating oil and residential fuel oil from 1,500 parts per million to 15 parts per million by 2018. In addition to sulfur reduction, the heating oil industry is also working on new fuel blends called Bioheat which contain between 2 and 20 percent renewable fuel.
The kerosene is a lighter oil. I think you would get more BTUs out of the heating oil. Just make sure that you are using the right fuel for the furnace that you have. Most now days would take heating oil.
Lower Heating Value (LHV) MJ/kg = 43.4 Higher Heating Value (HHV) MJ/kg = 46.5
Probably any other type of heating oil though you will lose capacity due to the different (lower) btu rating of other grades of heating fuel oil.
The heating value for diesel overheating oil ranges depends with the grade of oil. It ranges between 132,900 and 137,000 Btu/US gal.
Yes, home heating oil and diesel fuel are almost identical and can be used interchangeably. Home heating oil used in a diesel vehicle is subject to road tax and you can be fined if caught using it to avoid road tax.
