Question 1

How many units is a 200 mcg dose of KPV (5mg vial, 3ml diluent)?

Accepted Answer

12 units on a standard U-100 insulin syringe (0.12 ml). Mixing a 5mg vial of KPV with 3ml of bacteriostatic water gives a concentration of 1.67 mg/ml. On a U-100 insulin syringe that means: 200 mcg = 12 units · 250 mcg = 15 units · 500 mcg = 30 units.

Question 2

What is the concentration of 5mg of KPV in 3ml?

Accepted Answer

5mg ÷ 3ml = 1.67 mg/ml.

Question 3

Which syringe do these unit marks refer to?

Accepted Answer

A standard U-100 insulin syringe, where 100 units = 1 ml. On U-50 or U-30 syringes the same volume reads as half or 30% of the U-100 marks. These are mathematical conversions for organizational purposes only — not medical advice.

Dose	Draw volume	U-100 units
200 mcg	0.12 ml	12 U
250 mcg	0.15 ml	15 U
500 mcg	0.3 ml	30 U
