To calculate ppm of SO2 when using
potassium metabisulfite powder (58% SO2):
1 gram potassium metabisilfite = 30 ppm SO2 in 5
gallons
1.5 grams (1/4 teaspoon) potassium metabisulfite= 45
ppm SO2 in 5 gallons
Percent (%) = milliliters per 100
milliliters (ml/100ml) or grams per 100 milliliters (g/ml)
