Energy and work both have the same units, Nm or Joules. Work is the transformation of energy from one form to another. When you push an object along the ground, the work done is equal to the force (weight x coefficient of friction) times the distance. The energy used in pushing the object is converted into heat. If you lift a mass m a distance h, the work done is mgh (mg is the force, h the distance). The lifting energy is converted into potential energy. When the object falls, its velocity after traveling distance h is sqrt(2gh), and its kinetic energy is 1/2 mv^2 = 1/2 m * 2gh = mgh, showing that the work, the kinetic energy, and the potential energy are indeed of identical value.

1 BTU = 1054.35 joule
1 kilogram = 2.20462 pound
Therefore BTU/lb = 1054.35*2.20462 joule/kg = 2324.441097 joule/kg

1 Btu = 1054 J
1 lb = 0.45359237 kilograms
Btu/lb : J/kg

Hey shree,
To convert foot-pounds to joules, you multiply foot-pounds by 1.356. To convert pounds to kilograms, you multiply pounds by 2.2046. To convert foot-pounds to BTU's, you multiply foot-pounds by 1.286 times 10 to minus 3. From these, you should be able to work it out. Good Luck!
