← mg to units converter
5 mg is not one fixed number of units. 5 mg is 100 units at 5 mg/mL, 50 at 10 mg/mL and 33.3 at 15 mg/mL on a U-100 syringe. Arithmetic only, not medical advice.
Units = (dose ÷ concentration) × scale. On a U-100 syringe, 100 units = 1 mL. Arithmetic only — not medical advice.
5 mg in units by concentration
| Concentration | Volume | U-100 units |
|---|---|---|
| 2 mg/mL | 2.5 mL | 250 |
| 2.5 mg/mL | 2 mL | 200 |
| 5 mg/mL | 1 mL | 100 |
| 10 mg/mL | 0.5 mL | 50 |
| 15 mg/mL | 0.33 mL | 33.3 |
| 20 mg/mL | 0.25 mL | 25 |
| 30 mg/mL | 0.17 mL | 16.7 |
Values are U-100 syringe units, not mg. Amber values exceed 100 units, more than one standard 1 mL U-100 syringe holds.
5 mg in units by vial size and water added
| Vial | 1 mL water | 2 mL water | 3 mL water | 5 mL water |
|---|---|---|---|---|
| 5 mg | 100 | 200 | 300 | 500 |
| 10 mg | 50 | 100 | 150 | 250 |
| 15 mg | 33.3 | 66.7 | 100 | 166.7 |
| 20 mg | 25 | 50 | 75 | 125 |
| 30 mg | 16.7 | 33.3 | 50 | 83.3 |
Values are U-100 syringe units, not mg. Amber values exceed 100 units, more than one standard 1 mL U-100 syringe holds.
5 mg is one of the labeled tirzepatide doses shown on the tirzepatide dosage calculator.
Frequently asked questions
Is 5 mg always the same number of units?
No. The number of units changes with concentration. 5 mg is 100 units at 5 mg/mL, 50 at 10 mg/mL and 33.3 at 15 mg/mL on a U-100 syringe.
How many mL is 5 mg?
Divide the dose in mg by the concentration in mg/mL. 5 mg is 1 mL at 5 mg/mL, 0.5 mL at 10 mg/mL and 0.33 mL at 15 mg/mL.
What if 5 mg comes out above 100 units?
5 mg at 2 mg/mL is 250 units, or 2.5 mL. A 1 mL U-100 syringe holds 100 units, so this volume is more than one syringe holds.
