I guess you can also do a conversion from a 'normal' SG hydrometer?

I'm a little confused by all the above, as some of the calculations
don't seem to work out for me.

If a Balling unit is a 1% w/w sugar solution, then this is equivalent
to 10g of sugar per 1000g water, which by definition is then 10g
sugar per 1000mL water. True?

This being the case, 20 o Balling is 200g sugar per 1000mL. True?

OK then. My hydrometer has a little chart which comes with it,
giving SG readings, the corresponding sugar/L and potential alcohol
(%) - I can scan it in if you would like to see it.

This tells me (with a little maths on my part) that:
10 g/L sugar = SG 1.004 = 1 o Balling
100g/L sugar = SG 1.038 = 10 o Balling
200g/L sugar = SG 1.077 = 20 o Balling
800g/L sugar = SG 1.304 = 80 o Balling

Now, in your calculation, you say that:

Now is this is a bit different to my calculation (above) of 80 o
Balling = SG 1.304. Is this because of the extra stuff (non-sugar)
in the mollasses? Or have I stuffed something up?

Confused,

Matt

don't stir at all- there is no grain/fruit to mash down, anyway. It
typically takes about a week to ferment out and to begin clarifying on it's

Hi everyone,

After all the discussion recently about Brix, Balling, SG and sugar,
I went away and a bit of searching and maths.

Heres what I found:

a) Brix, Balling and Plato are all measures of specific gravity of
sugar solutions, where 1 unit is equivalent to 1% w/w solution
sugar. So 1o = 1% sugar; 20o = 20% sugar

b) You can convert Brix/Balling/Plato to SG:

{ Brix /(258.6-([Brix/258.2]*227.1)} + 1 = Specific gravity
or
Brix = 258.6 / [ 0.88 + 1/(sg-1)]

So using this, I have made up two tables - one for converting SG to
Brix, and the other from Brix to SG. I have expanded the tables so
that the sugar/water quantities to make up the solutions of a
specific SG or Brix value can be done in three ways:
i) Number of grams sugar added to water to make up 1000g of solution
ii) Number of grams of sugar added to 1000g (1000mL) water to make
up the solution
iii) Number of grams of sugar made up to a volume of 1000mL with water
