Pounds is not a measurement of weight it is a non-SI measurement for mass. You actually weigh a lot more then you think. And though if the gravity changes so does your weight however not your mass, which stays the same (if special relativity is disregarded, however the difference in mass between the earth and moon is not large enough to make any large difference anyway). Therefore I could finish here and answer your question with 100 pounds. But I understand what you meanand therefore you would actually weigh 73 kg*m/s^2. On earth you would weigh 441 kg*m/s^2.
