how much salt per how many ppm difference?

[algy1943]

So is there a calculator, chart, or something that will help determine how much salt to add to raise the reading on the refractometer one ppt, based on X gallons?

OK... yeah... no salt is zero and about 1/2 cup is 35 ppt... I get that.. I'm just lazy today and am looking for one already done.

I use .02 g per litre , which is equal to .222gallon (.02g to .222gallon)
