How many pounds is 1000 FHM?

Just as the title states... Some people buy FHM in pounds and some in thousands. What's an average poundage for 1000 FHM?

From Bill Cody in another post from last year:

Plan on 200-250 per lb. In the fall new crop FHM are usually somewhat smaller 1.7-2.2" and 350-250/lb.

Thanks!
