How much salt in a cup of salt?

WHOA! Here's a fascinating article about why it may be important to weigh it. The author of this article runs out of salt, buys a different brand than usual, and proceeds to oversalt everything. Consistently. So he does a really neat experiment, described below.

So I got out a one-cup measure and a scale, and I weighed similar volumes of Morton’s and Diamond Crystal kosher salts, plus regular table salt, generic coarse sea salt and Malden sea salt from England (included for no reason other than that I think it is the most beautiful of salts). Here’s the outcome, rounded off to the nearest five grams or eighth of an ounce (no, this is not a scientific inquiry):

• Morton’s kosher: 250 grams (8 3/4 ounces)
• Diamond Crystal kosher: 135 grams (4 3/4 ounces)
• Table salt: 300 grams (10 5/8 ounces)
• Coarse sea salt: 210 grams (7 3/8 ounces)
• Malden sea salt: 120 grams (4 1/4 ounces)
• Malden sea salt: 120 grams (4 1/4 ounces)
