This chart is based on figures from Morton Salt. Other brands or degrees of coarseness may produce different measurements.
Note: Pickling salt contains anti-caking agents. Kosher salt may be used in its place, but check the label to make sure there are no additives. Also, the grains are different so adjustments have to be made to the amount. Morton has anti-caking agent in their kosher salt, so the quality of the pickles might suffer. Their conversion chart lists 1 1/4 cups of kosher is equal to 1 cup of pickling and canning salt.
Diamond Crystal kosher salt has no anti-caking agents, but it is coarser than the Morton brand so you will have to measure by weight to get the required amount.
