Frequently Asked Questions

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 the 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.
