3 mg vial + 1 mL bacteriostatic water: units chart
A 3 mg vial mixed with 1 mL of bacteriostatic water holds 3,000 mcg per mL. This is a middle-strength mix: each unit holds 30 mcg, so most doses in the table land between 2 and 100 units on a 1 mL syringe.

- Convert the vial amount to mcgmg × 1,000 = mcg3 mg × 1,000 = 3,000 mcg
- Convert the dose to mcgmg × 1,000 = mcg0.25 mg × 1,000 = 250 mcg
- Concentrationvial (mcg) ÷ water (mL) = mcg per mL3,000 mcg ÷ 1 mL = 3,000 mcg/mL (3 mg/mL)
- Volume to drawdose (mcg) ÷ concentration (mcg/mL) = mL250 mcg ÷ 3,000 mcg/mL = 0.0833 mL

Worked example: 300 mcg
- Convert the vial amount to mcg: 3 mg × 1,000 = 3,000 mcg
- Concentration: 3,000 mcg ÷ 1 mL = 3,000 mcg/mL (3 mg/mL)
- Volume to draw: 300 mcg ÷ 3,000 mcg/mL = 0.1 mL
- Units to draw: 0.1 mL × 100 units/mL = 10 units
- Amount in each unit: 3,000 mcg/mL ÷ 100 units/mL = 30 mcg per unit (0.03 mg)
- Doses in the vial: 3,000 mcg ÷ 300 mcg = 10 full doses
Draw to the 10-unit mark on a U-100 syringe. The same 300 mcg dose is 5 units with 0.5 mL of water and 15 units with 1.5 mL of water, compared with 10 units with 1 mL.
Frequently asked questions
What is the concentration of a 3 mg vial with 1 mL of water?
A 3 mg vial mixed with 1 mL of water holds 3,000 mcg per mL. Each unit on a U-100 syringe holds 30 mcg.
How many units is 300 mcg with a 3 mg vial and 1 mL of water?
It is 10 units on a U-100 syringe, which is 0.1 mL of the mixed liquid.
What is the smallest dose you can measure well with a 3 mg vial and 1 mL of water?
About 60 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 3 mg vial and 1 mL of water?
The whole vial fits: 3,000 mcg is 100 units on a U-100 syringe.
How many doses does a 3 mg vial with 1 mL of water give?
Divide 3,000 mcg by your dose and round down: 10 full doses of 300 mcg, or 7 of 400 mcg.
