How much does a newspaper weigh in grams and kilograms?

It could vary if the newspapers are compacted or not. If they were tightly placed on on top of another an estimate would be about 216 lbs. This is based on a 4oz 12x18x.25" newspaper of which aproximately 864 would fit in a cubic yard. Newpaper sizes vary which could vary the amount that would fit in a cubic yard.
