Tim,
LOL....
The reason I came up with the list of salt conversions was to be able to use them with baker's percents to convert small amounts of different salts to volumes. Otherwise, you would need a special scale capable of weighing small quantities of lightweight ingredients. Originally I used a calculator to do the conversions but have since programmed many of the conversion factors into a spreadsheet, which now automatically does all the weight-to-volume conversions for ingredients like salt.
