As a dry measure the answer would be 8 ounces. If you want a weight it would depend on what type of salt you were to weigh, table salt, kosher salt, etc. I weighed a cup (8 ounces) of iodized table salt on my digital scale and it weighed 15.2 ounces.
Pickling salt is the same as table salt but without iodine and caking agents added. Salt that is labeled "kosher salt" may be free of these additives and can be used in place of pickling salt but you'd have to check the package labeling to confirm the lack of additives.
It depends on the brand of kosher salt you will be using as it varies in strength. if you use Morton's Kosher salt use 2 cups to = 1 pound, or if you use Diamond Crystal Kosher Salt 3 cups to = 1 pound.
