0.5 lb ,or whatever . The big issue also is what I said in my last post:

I tried kgs and lb, tried to enable and disable zone rates, when I get results of my calculation when zone rates is disabled, I get the calculation based on each item in a box, even when the check box is disabled for ready to ship in Zen Cart, and when I enable zone rates, I get the calculation by zone rate, and on top of the result, I get different shipping options based on X times number of items purchased in individual boxes.
