Dose to volume calculator
Use a target dose and concentration you have independently verified.
Calculated volume
Enter your verified concentration and target dose to calculate.
mL
U-100 markings
Check the inputs, every time.
This tool converts units. It does not determine an appropriate dose or whether a product is safe to use.
How the arithmetic works
Convert mcg to mg by dividing by 1,000. Divide the resulting mg by the concentration in mg/mL to obtain mL. For an explicitly selected U-100 syringe, multiply mL by 100 to obtain scale markings.
International Units (IU) express biological activity for specific substances. This tool does not convert peptide mass to IU. It does not calculate a dose from body weight, infer concentration from a product name, or round a result to a usable injection.
Unit confusion can cause serious dosing errors. See the FDA explanation of dose, volume and syringe-unit errors.
