Question: how much is 1/2 cc on a syringe?
Answer: U100 insulin syringe. U100-concentrated insulin has 100 units per ml of liquid, and should be used with U100 syringes. Cubic centimeters (cc's) and milliliters (mL's) are interchangable, so syringes marked 1ml equals 1cc; 0.5 ml equals 1/2cc. 3/10cc equals 0.3ml.
