Insulin syringe unit converter
Convert a volume to syringe units, or units back to a volume — the two directions of the same U-100 scale, with no vial or dose involved at all.

On a U-100 insulin syringe, 100 units equal 1 mL, so each unit is 0.01 mL. General dose math only — not medical advice. Intended solely for substances you lawfully possess. Results reflect the values you entered; always confirm dosing with a qualified professional.

A U-100 insulin syringe is marked in 100 units per milliliter, so each unit equals 0.01 mL. This converter does nothing but that multiplication or division, in whichever direction you need: type a volume to see it in units, or type a unit count to see it in milliliters.
It doesn't ask what's in the syringe. It's the same scale printed on the barrel of a standard U-100 syringe, turned into a calculator so you don't have to do the multiplication by hand.
If you are considering using any injectable peptide, you must consult with a licensed physician or qualified healthcare provider before purchasing, reconstituting, or administering any injectable product. This applies regardless of whether a prescription is required in your jurisdiction. Injectable peptides carry additional risks including but not limited to infection, allergic reaction, nerve damage, and adverse events from improper reconstitution, contaminated supplies, incorrect technique, or dosing errors.
Never do this math twice.
Peptade keeps the numbers you enter for each compound, so its reconstitution tool fills them in for you next time — from your own entries, never from a catalog.

How it works
Step 1
Pick a direction
Enter a volume in the first field, or a unit count in the second — you can use either one independently.
Step 2
Let it convert
The tool multiplies or divides by 100, the fixed U-100 scale, with no other input involved.
Step 3
Read the other value
See the matching figure in the other unit, ready to compare against your syringe barrel.
Worked example
- 0.30 mL × 100 = 30 units
- 45 units ÷ 100 = 0.45 mL

Frequently asked questions
It's the standard scale for insulin syringes: the barrel is marked so that 100 units equal 1 mL, regardless of what liquid is inside.
Yes — those smaller syringes use the same U-100 scale, just with fewer total units printed on the barrel.
The math is the same for any liquid; the converter just relates milliliters to units, without knowing or needing to know what the liquid is.
