Energy Unit Comparison One of the difficulties of reading articles about energy resources is the plethora of units used. This is an attempt to give a comparison of some commonly quoted energy units. You may enter a number in any of the boxes to calculate the comparisons in other units. Joules x 10^ .....ft-lb x 10^ ..........calorie x 10^ ...............BTU x 10^ ....................kWh x 10^ .........................gallons of gasoline x 10^ ..............................1000 cu ft of natural gas x 10^ ...................................barrel of oil x 10^ ........................................ton of coal x 10^ The energy values for the common fuels are nominal values since the energy content of these fuels varies with the source.
