weight calculation anyone?

for one sq ft of chopped strand mat with resin, 3/16" thickness.

My digital scale is broken.

You’d need a density to go along with the data you have to get an accurate weight unless you’re looking for an estimate

W1 is weight with resin, W2 is weight of cloth without resin.

W1-W2 divide by W1 x 100=

hope it helps, this is wet resin content.
