UNITS OF MEASUREMENT
 
Click here for http://www.eia.doe.gov/kids/unitsindex.html Physical units reflect measures of distances, areas, volumes, heights, weights, mass, force, impulse and energy. Different types of energy are measured by different physical units: barrels or gallons for petroleum; cubic feet for natural gas; tons for coal; kilowatt-hours for electricity. To compare different fuels, we need to convert the measurements to the same units. In the United States, the unit of measure most commonly used for comparing fuels is the British Thermal Unit (Btu), which is the amount of energy required to raise the temperature of one pound of water one degree Fahrenheit.
