Energy can be defined as a property of physical objects or fields to do work on other physical systems, while the work is defined as a force acting through a distance and consequently energy is equivalent to the ability to exert pulls or pushes against the basic forces of nature, along a path of a certain length. 

In the International System of Units Energy and Work are measured in Joules (J), however in specific fields other units are also often used (like kilowatt-hours and kilocalories).

These online unit converters are designed to support fast and accurate conversion among several units of energy, from one system into another.
