The best answer I have found is that one kw of electricity = .024 gallons of USA No. 2 Heating Oil, or one gallon of the oil = 40.6 kw. It is also important to understand the efficiency of the device which converts the fuel energy to the desired product, such as heat or motion. My source for the above is http://www.energykinetics.com/heatingfuelcomparisons.html
A therm is a unit of measurement used to quantify heat energy. It is equal to 100,000 British Thermal Units (BTUs) and is often used in the context of natural gas consumption or heating systems.

look for therm
100 therm is more then 3.20 therm
there are 100.000 btu's in a therm.
therm means heat
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.
One therm equals 100,000 BTUs.
Therm-O-Disc was created in 1947.
The Greek root "therm" means "heat".
For gas and oil water heaters, you need to know the unit cost of fuel by BTU (British thermal unit) or therm (1 therm = 100,000 BTU). Then use the following calculation: 365 X 41045/EF X Fuel Cost (BTU) = estimated annual cost of operation http://apps1.eere.energy.gov/consumer/your_home/water_heating/index.cfm/mytopic=13010
therm/thermo means "heat" and this is valid because I looked it up in the Webster's Dictionary.
