MDF Weights

Hey everyone i found this pdf and of mdf weights I think its pretty good any chance that anyone can confirm these I believe they are close and i do realize that each manufacter will have woods that will weigh different amounts

But i am hoping to use this chart to calculate shipping costs

on that note can anyone provider me with info on the best way to ship a 24x24 inch square of mdf I am talking packing material, mail service, etc
mdf panel weights.pdf (196.6 KB)

and correct me if i am wrong but according to this chart a 24x24 square of .25" mdf will weight 3.76 pounds?

I make it 3.84 lbs but allow for conversion from the metric weight tables I have.
