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
One Calorie (20°C) is the amount of energy needed to raise the temperature of 1 gram of air-free water from 19.5 to 20.5 °C at atmospheric pressure.
