One Kilojoule is 1,000 Newton Metre, ie the work done or energy transfered to an object when a 1,000 Newton force acts on it over one metre. It can also be defined as the heat energy dissipated by a current of 1,000 amperes passing through a one Ohm resistor for one second
One BTU (IT) was defined by the Fifth International Conference on the Properties of Steam to be exactly 4.1868 J
