mcg to units charts
Converting mcg to units depends on your concentration: units = mcg ÷ (10 × mg/mL) on a U-100 syringe. Pick an amount for its full chart, or use the peptide calculator for any vial, water and dose.
mcg to units at common concentrations
| Amount | 1 mg/mL | 2.5 mg/mL | 5 mg/mL |
|---|---|---|---|
| 50 mcg | 5 units | 2 units | 1 units |
| 100 mcg | 10 units | 4 units | 2 units |
| 200 mcg | 20 units | 8 units | 4 units |
| 250 mcg | 25 units | 10 units | 5 units |
| 300 mcg | 30 units | 12 units | 6 units |
| 500 mcg | 50 units | 20 units | 10 units |
| 750 mcg | 75 units | 30 units | 15 units |
| 1 mg | 100 units | 40 units | 20 units |
| 2 mg | over 100 | 80 units | 40 units |
| 2.5 mg | over 100 | 100 units | 50 units |
| 5 mg | over 100 | over 100 | 100 units |
| 10 mg | over 100 | over 100 | over 100 |
How do you convert mcg to units?
Work out your concentration, then divide. A 5 mg vial with 2 mL of water is 2.5 mg/mL, so 250 mcg is 250 ÷ (10 × 2.5) = 10 units on a U-100 syringe.
Other concentrations in the charts: 0.5 mg/mL, 1 mg/mL, 2 mg/mL, 2.5 mg/mL, 5 mg/mL, 10 mg/mL. For mg, multiply by 1,000 first (mg to mcg converter).

Frequently asked questions
How do you convert mcg to units?
Divide the mcg by ten times your concentration in mg/mL: units = mcg ÷ (10 × mg/mL). At 2.5 mg/mL, 250 mcg is 250 ÷ 25 = 10 units on a U-100 syringe.
How many mcg are in one unit?
One U-100 unit is 0.01 mL, so it holds one hundredth of your concentration: 25 mcg at 2.5 mg/mL, or 50 mcg at 5 mg/mL.
Is a unit a measure of weight?
No. A syringe unit is a volume mark. How many mcg it holds depends on how much peptide is dissolved in each mL.
