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 foot pound is the work done by a force of one pounl acting through a distance of one foot, in the direction of the force. It equates to 1.355 817 948 331 4004 joules
