Most scoops from lots of different products, Protein and other, are either 1 Tbl or 2 Tbl.
If that helps.
1 scoop of most brands of protein powder range from about 18 grams of Protein to 22 grams of Protein.
You can not convert volume measure (tBl) to weight measure (grams),
And besides, the amount of protein in Protein powders is not the weight of one scoop,
but the weight of the Protein in that scoop measure.
