Questions

How many mg is 75 units?

75 units on a U-100 syringe is 0.75 mL. Multiply that by the concentration: at 5 mg/mL it is 3.75 mg, at 10 mg/mL it is 7.5 mg.

How many mL is 75 units?

0.75 mL. On a U-100 insulin syringe 100 units is 1 mL.

How many mcg is 75 units?

Work out the mg first, then multiply by 1,000. At 5 mg/mL, 75 units is 3.75 mg, which is 3,750 mcg.

How do I find the concentration of my vial?

Divide the mg printed on the vial by the mL of water that was added. A 10 mg vial with 2 mL added is 5 mg/mL. If the vial was dispensed as a liquid, the mg/mL is printed on the label.
