About this tool
The dosing-unit converter translates between the units you run into with injectable compounds: insulin units (U), micrograms (mcg), milligrams (mg), milligrams per kilogram (mg/kg), and HCG international units (IU). Paste a value, pick the source and target units, and it returns the converted dose. It prevents the common and dangerous mistakes that come from mixing unit systems.
How to use it

- 2 Pick the source unit and the target unit.
- 3 Enter your bodyweight if you need mg/kg conversions.
- 4 Read the converted dose and double-check it against your original value.
Frequently asked questions
How many insulin units are in 1 mL?
On a U-100 insulin syringe, 100 units equals 1 mL. So 10 units is 0.1 mL, and 1 unit is 0.01 mL.
How do I convert mcg to mg?
Divide by 1,000. So 500 mcg equals 0.5 mg, and 1,000 mcg equals 1 mg. The tool does this for you.
