Using salinity refractometer for homebrewing (Salt -> Brix Conversion)

[azaxev]

I have salinity refractometer, it's tested and works well. New to homebrewing, I was looking for a way to use it instead of keeping multiple identical instruments with different indicator scale.

At first was going to make conversion table through refractive index, and then found out someone already done it. Thanks to Dr. Edward B. Walker from Weber State University

Simplified conversion: Brix = 1.15 x Salt
