How to remove the Weight Limit and Product Weight 0 error

[dantoksg]

Hi All,
Could someone advice how to remove the product weight 0 modification?
My products are small items and their weight are suppose to be 0.0001 and such.

If i am unable to remove the mod, i tried to change the weight to grams. However the system does not allow weight more than 1000.

Can someone kindly guide me in the right way on what to change to remove the 1000lb weight limit and remove the product weight 0 to be treated like a virtual product? Or which ever easier so that we can do shipping calculated properly.
