# Calculations

## KI and I−

130 grams KI holds 100 grams I

This means that you divide the amount of KI by 1.3 to get the amount of I.

Costs of 1 liter of home made Lugols:

50 grams of iodine costs (89 + 31.91)/250 * 50 = USD 24.18

130 grams of KI costs (113.11 + 31.91) / 1000 * 130 = USD 18.85

Together: 24.18 + 18.85 = USD 43.03 for 1 liter of Lugols

Costs of 1 liter of SSKI home made:

Wiki: the resulting SSKI solution will contain about 1.40 gram (1400 mg) KI per milliliter (mL) of solution.

1 liter of SSKI holds 1400 gram KI, this equals 1400/ 1.3 = 1076.92 gram I.

1400 gram KI costs (113.11 + 31.91) / 1000 * 1400 = USD 203.03

Costs compared on 50 mg daily (I and I2 combined):

• Iodoral: 67.20 / 90 = USD 0.75 per day
• Bought Lugols 12% holds 12 gram per 100 ml. This equals 50 mg per 0.42 ml.
This costs 409.37/1000*0.42 = USD 0.17  per day
• Home made Lugols 15% holds 15 gram per 100 ml. This equals 50 mg per 0.33 ml.
This costs 43.03 /1000 * 0.33 = USD 0.014 per day.
• Home made SSKI holds 1076,92 gram I- per liter. A liter costs USD 203.3.
50 mg costs 203.3 / 1076.92 / 1000 * 50 = USD 0.0094 per day.
