- Convert the vial amount to mcgmg × 1,000 = mcg10 mg × 1,000 = 10,000 mcg
- Convert the dose to mcgmg × 1,000 = mcg0.25 mg × 1,000 = 250 mcg
- Concentrationvial (mcg) ÷ water (mL) = mcg per mL10,000 mcg ÷ 3 mL = 3,333.33 mcg/mL (3.33333 mg/mL)
- Volume to drawdose (mcg) ÷ concentration (mcg/mL) = mL250 mcg ÷ 3,333.33 mcg/mL = 0.075 mL

Worked example: 300 mcg
- Convert the vial amount to mcg: 10 mg × 1,000 = 10,000 mcg
- Concentration: 10,000 mcg ÷ 3 mL = 3,333.33 mcg/mL (3.33333 mg/mL)
- Volume to draw: 300 mcg ÷ 3,333.33 mcg/mL = 0.09 mL
- Units to draw: 0.09 mL × 100 units/mL = 9 units
- Amount in each unit: 3,333.33 mcg/mL ÷ 100 units/mL = 33.33 mcg per unit (0.03333 mg)
- Doses in the vial: 10,000 mcg ÷ 300 mcg = 33 full doses
Draw 9 units on a U-100 syringe, halfway between the 8- and 10-unit marks. The same 300 mcg dose is 7.5 units with 2.5 mL of water and 15 units with 5 mL of water, compared with 9 units with 3 mL.
Frequently asked questions
What is the concentration of a 10 mg vial with 3 mL of water?
A 10 mg vial mixed with 3 mL of water holds 3,333.33 mcg per mL. Each unit on a U-100 syringe holds 33.33 mcg.
How many units is 300 mcg with a 10 mg vial and 3 mL of water?
It is 9 units on a U-100 syringe, which is 0.09 mL of the mixed liquid.
What is the smallest dose you can measure well with a 10 mg vial and 3 mL of water?
About 66.67 mcg, which fills 2 units on a U-100 syringe. Smaller amounts are hard to read; a vial mixed with more water spreads them over more units.
What is the largest dose that fits a 1 mL syringe with a 10 mg vial and 3 mL of water?
3,333.33 mcg, which fills all 100 units of a 1 mL U-100 syringe. Larger doses need more than one draw or a stronger mix.
How many doses does a 10 mg vial with 3 mL of water give?
Divide 10,000 mcg by your dose and round down: 33 full doses of 300 mcg, or 25 of 400 mcg.
