Energy content of biofuel (J/kg) or equivalent units. Energy density is the amount of energy stored in a fuel per unit volume, expressed in SI units as joule per litre (J/L) or equivalent units. The table below includes entries for popular substances already used for their energy, or being discussed for such use. The second column shows specific energy, the energy content in megajoules per unit of mass in kilograms, useful in understanding the energy that can be extracted from the fuel. The third column in the table lists energy density, the energy content per liter of volume, which is useful for understanding the
Work unit use of individual behavior as the unit of study in Radical behaviorism, and the meme in anthropology. The influence of a work unit on the life of an individual was substantial and permission had to be obtained from the work units before undertaking everyday events such as travel, marriage, or having children.
