You need a scale for accurate measurement. Personally, I don't think it's worth my time or money to buy a scale so I just estimate it by volume. If you want to get as accurate as possible, I would not even use the scoop, but rather look at the volume of the scoop at the bottom. It will give it in cubic centimeters. 1 table spoon is 15 mL which is 15 cc. So if you have a 72 cc scoop that yields 25 g of protein, it is the same as 4.8 tablespoons. 1 g of protein = .192 tablepsoons, so 10 g of protein = 1.92 tablespoons.
