6 mg vial + 1.5 mL bacteriostatic water: units chart
A 6 mg vial mixed with 1.5 mL of bacteriostatic water holds 4,000 mcg per mL. This is a middle-strength mix: each unit holds 40 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 = mcg6 mg × 1,000 = 6,000 mcg
- Convert the dose to mcgmg × 1,000 = mcg0.25 mg × 1,000 = 250 mcg
- Concentrationvial (mcg) ÷ water (mL) = mcg per mL6,000 mcg ÷ 1.5 mL = 4,000 mcg/mL (4 mg/mL)
- Volume to drawdose (mcg) ÷ concentration (mcg/mL) = mL250 mcg ÷ 4,000 mcg/mL = 0.0625 mL

Worked example: 400 mcg
- Convert the vial amount to mcg: 6 mg × 1,000 = 6,000 mcg
- Concentration: 6,000 mcg ÷ 1.5 mL = 4,000 mcg/mL (4 mg/mL)
- Volume to draw: 400 mcg ÷ 4,000 mcg/mL = 0.1 mL
- Units to draw: 0.1 mL × 100 units/mL = 10 units
- Amount in each unit: 4,000 mcg/mL ÷ 100 units/mL = 40 mcg per unit (0.04 mg)
- Doses in the vial: 6,000 mcg ÷ 400 mcg = 15 full doses
Draw to the 10-unit mark on a U-100 syringe. The same 400 mcg dose is 6.7 units with 1 mL of water and 13.3 units with 2 mL of water, compared with 10 units with 1.5 mL.
Frequently asked questions
What is the concentration of a 6 mg vial with 1.5 mL of water?
A 6 mg vial mixed with 1.5 mL of water holds 4,000 mcg per mL. Each unit on a U-100 syringe holds 40 mcg.
How many units is 400 mcg with a 6 mg vial and 1.5 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 6 mg vial and 1.5 mL of water?
About 80 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 6 mg vial and 1.5 mL of water?
4,000 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 6 mg vial with 1.5 mL of water give?
Divide 6,000 mcg by your dose and round down: 15 full doses of 400 mcg, or 12 of 500 mcg.
