Hydrometer Calculate
THE HYDROMETER Calculate
Basic facts:
1 litre of water weighs 1 kg (1 000 grammes)
1 litre of alcohol weighs 0.8 kg (800 grammes)
1 litre of water weighs 1 000 grammes = which is
neither more or less than 1 kg. That gives 1000 degrees
on the hydrometer (specific gravity).
1 litre of alcohol weighs 800 grammes. This would be 800
degrees on the hydrometer (specific gravity) if it had
a scale long enough.

1 litre alcohol = 800 grammes

10% alcohol/water – mixture
100 ml alcohol x weight 0.8 = 80 grammes
900 ml water = 900 grammes
80
900
980 grammes
980 grammes is (specific gravity) 980 hydrometer degrees
