Measure High (off-scale) °Brix by Dilution
Details: A sample of high sugar juice can be diluted in order that it can be read on equipment with a limited scale. However because the °Brix scale is calibrated as %w/w, but the dilution is carried out by measuring volume, the reading cannot simply be multiplied by the dilution to obtain the °Brix of the juice. This calculator corrects for this, allowing such dilutions to be used.
Note on SG: If measuring a juice using SG (specific gravity), simple multiplication is possible. For example, a sample diluted to 50% with distilled water, which reads 1.090, has a gravity of 1.180.
The calculations involved in this calculator are the same as those used in the gravity/density/sugar conversions. First the measured °Brix is used to calculate the gravity, which is then combined with the °Brix to calculate the dissolved solids. The dissolved solids is multiplied by (100/d), where d is the dilution percentage. So a dilution of 50% would mean multiplying the dissolved solids by 2. This number is then converted back to °Brix.
