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.
