Often the confusion comes when using measurements ( tsp, TBS,etc) vs. actual elemental/ weight of a product.
Nancy's post broke it down perfectly:
450# needs 6gm SODIUM( using salt with 39% sodium ) which when using a gram scale=15.3gm of salt ~ this is gram weight.
If sweating for an hour+, then will need an additional 4.48gm of SODIUM, which =11.2 gram weight of 39% salt.
Purchase a gram scale! They cost less than $20 and then you will be able to weigh 15.3 gm of salt, and then use an implement to measure out the correct dose.
I have 4 different brands of measuring spoons...each one holds a different amount of product.
Gram scale= no question about how much you are giving.
