One Joule is 1 Newton Metre, ie the work done or energy transfered to an object when a one Newton force acts on it over one metre. It can also be defined as the heat energy dissipated by a current of one ampere passing through a one Ohm resistor for one second
The thermochemical calorie was defined in 1930 by Frederick Rossini as 4.1833 joules. With the change to absolute electrical units in 1948, the thermochemical calorie was redefined to 4.184 joules, to keep the same quantity of energy represented by it
