Btu

One BTU is the energy required to heat 1 avoirdupois pound of liquid water by 1 degree Fahrenheit, at a pressure of one atmosphere.

Kilojoules

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
