One BTU is the energy required to heat 1 avoirdupois pound of liquid water by 1 degree Fahrenheit, at a pressure of one atmosphere. The Btu (mean) uses a result averaged over water temperatures 0 to 100 °C (32.0 to 212.0 °F) which is approx. 1055.87 J
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
