OK, You asked for it.
The exact formula (minus raised exponents) for converting specific
gravity to Brix is as follows:
°P = 135.977 x sp gr(3power) -630.272 x sp gr (2nd power) +1114.14 x sp
gr - 616.868.
I use brix to watch the thinning runoff and a hydrometer to sample O.G.
and F.G. The third scale on the hydrometer is a fairly accurate
estimate alcohol by (I believe) weight.
My old mercury lab thermometer broke but the mercury was recycled.
