You will note that a pound is a unit of mass, not of force. Its metric equivalent, 453.59237 grams, is a DEFINITION of the pound. (source: Handbook of Mathematical Functions, Abramowitz and Stegen.) The pound-force is given as 4.44822 newtons ( not a definition ) This gives "g" a value of 9.80665 m/sec/sec ( to make a pound weigh a pound.) The measured value of "g" varies from 9.780350 at the equator to 9.832072 at the poles. Its value at 45 degrees is 9.806154, which is where the pound-force value comes from, I suspect.
