  Pound (mass) - Wikipedia, the free encyclopedia
The pound is the name of a number of units of mass, all in the range of 300 to 600 grams.
In many countries that use the SI or metric system, the pound (or its translation, for example, the German Pfund, the French livre, the Dutch pond, the Spanish and Portuguese libras, or the Chinese jin) is used as an informal term for half of a kilogram, therefore for this case the pound is 500 grams.
Pounds are also used for the force definitions of weight, as well as for other forces, in which the pound force is a unit of force equal to 4.448 newtons.

 Work, energy, and lifting up   (Site not responding. Last check: 2007-10-13)
Note that the work, or energy, required to lift something is its weight ("weight" is the force of its mass times the gravitational accelleration where it's at) times the height through which it is lifted, the force exerted upward being equal in magnitude to its weight.
Note that this is the same amount of energy which would be given up by the one pound mass if it returns to rest again on the equator.
In more personal terms, for a 165 pound person to be lifted similarly, the energy added to the person, expresed in electrical power cost terms, would theoretically be $119.
