Work, Energy and Power
The unit of Energy is the same as of Work, i.e. Joules. Energy is found in many things, and thus there are different types of energy. All forms of energy are either kinetic or potential. The energy in motion is known as Kinetic Energy, whereas Potential Energy is the energy stored in an object and is measured by the amount of work done.

In order to gain an intuitive appreciation for the relative magnitudes of the different forms of energy we consider the (tongue-in-cheek) example of an attempt to cook a turkey by potential energy. The turkey is brought to the top of a 100 m building (about 30 stories) and then dropped from the ledge. ... [Pa], however practical units are ...
Energy Units and Conversions
Energy Units and Conversions. Power = Current x Voltage (P = I V) 1 Watt is the power from a current of 1 Ampere flowing through 1 Volt. 1 kilowatt is a thousand Watts. 1 kilowatt-hour is the energy of one kilowatt power flowing for one hour. (E = P t). 1 kilowatt-hour (kWh) = 3.6 x 10 6 J = 3.6 million Joules.

Joule
The joule (pronounced / ˈ dʒ uː l /, JOOL or / ˈ dʒ aʊ l / JOWL; symbol: J) is the unit of energy in the International System of Units (SI). It is equal to the amount of work done when a force of one newton displaces a mass through a distance of one metre in the direction of that force. It is also the energy dissipated as heat when an electric current of one ampere …

In 1843, James Prescott Joule independently discovered the mechanical equivalent in a series of experiments. The most famous of them used the "Joule apparatus": a descending weight, attached to a string, caused rotation of a paddle immersed in water, practically insulated from heat transfer. It showed that the gravitational potential energy lost by the weight in descending was equ…
2.4: Energy and Its Units
Because calories and joules are both units of energy, however, the calorie is now defined in terms of the joule: 1 cal = 4.184 J exactly (2.4.8) 1 J = 0.2390 cal (2.4.9) In this text, we will use the SI units—joules (J) and kilojoules (kJ)—exclusively, except when we deal with nutritional information.
2.1: The Units of Energy
Page ID. The SI unit for Energy is the joule, usually abbreviated J. One joule is equal to one kilogram meter squared per second squared: 1 J = 1kgm2 s2 1 J = 1 k g m 2 s 2. Anything that is energy can be written as a number of joules. However, this isn''t the only unit for energy. You are probably more familiar with another unit, the kilocalorie.

Energy is defined via work, so the SI unit of energy is the same as the unit of work – the joule (J), named in honour of James Prescott Joule and his experiments on the mechanical equivalent of heat. In slightly more fundamental terms, 1 joule is equal to 1 newton metre and, in terms of SI base units An energy unit that is used in atomic physics, particle physics and high energy physics is the electronvolt
