Question: How do I convert fuels from one unit of measure to another—from gallons to barrels, for example?

To compare fuels, you must convert physical units of measure, such as weight or volume, and energy content measures of each fuel to comparable units. One way to compare different fuels is to convert them into British thermal units (Btu). The Btu is the amount of energy required to raise the temperature of 1 pound of water 1 degree Fahrenheit. To convert units of measure, use the Energy Calculator  Common Units and Conversions.

Question: How do I compare heating fuels?

When choosing a heating system for a new home or
replacing an existing system, consumers often want
to compare the cost of heating fuels. Because fuels
are measured and sold in different units such as gallons
of oil, therms of natural gas, or kilowatt hours (kWh)
of electricity, comparing the price of dissimilar
units is not useful.
A more useful comparison is the fuel cost per amount
of heat produced. EIA’s Heating
Fuel Comparison Calculator (Excel) helps you
make this comparison. It factors in the relative price
based on the fuel heat content and the heating appliance’s
efficiency. The Comparison Calculator provides stepbystep instructions, including how
to find cost and efficiency data to use with the Calculator.
(The Calculator is a Microsoft Excel
spreadsheet. You can use it online or save it to your
hard drive and then open it in Excel.)
In choosing a heating system, don’t rely solely
on cost. Numerous factors will determine the heating
system that best meets your needs. The Comparison
Calculator (Excel) provides links to additional
information that will help you choose a heating system.
