How many ounces seasoning salt equals one gallon?

Answer 1

Do you mean common table salt? Are we talking U.S gallons? If this is not your question, please clarify and resubmit.

1 U.S. gallon of water weighs 8.32487 pounds, or 133.198 ounces. Table salt (in crystal form, as in your salt shaker) has a specific gravity of 1.154, which gives about 154 ounces.
