How It Works
Understanding the math
01
Concentration
Your vial quantity (mg) divided by BAC water added (ml) gives concentration in mcg/ml. A 5 mg vial in 1 ml = 5,000 mcg/ml.
02
Volume per dose
Your desired dose (mcg) divided by concentration (mcg/ml) gives the exact draw volume. 50 mcg ÷ 5,000 mcg/ml = 0.01 ml.
03
Unit marks (U-100)
Standard insulin syringes hold 100 units per ml. Multiply volume in ml by 100 to get the unit mark. 0.01 ml × 100 = 1 unit mark.
