THE CALCULATION
VOLUME FOR ENTERED TARGET
U-100 SCALE EQUIVALENT
Select a U-100 syringe size to show its scale equivalent.
U-100 scale units represent volume, not product potency or IU. Results are not rounded to syringe tick marks.
≈ Rounded to 10 significant digits. Calculations use the entered values without intermediate rounding.

How the math works
Concentration
Labeled amount ÷ water volume added
The labeled amount in mg divided by the entered water volume in mL gives concentration in mg/mL.
Volume for an entered target
Target amount ÷ concentration
The entered target in mg divided by concentration in mg/mL gives volume in mL. A target in mcg is divided by 1,000 first.
U-100 scale conversion
Volume in mL × 100
100 scale units = 1 mL on U-100 syringes. The selected barrel size determines capacity. This conversion does not apply to other syringe scales.
The math assumes the labeled amount is uniformly distributed and the added water volume equals the final solution volume. Actual final volume may differ; results depend on this assumption. The calculator does not select a target amount or assess whether one is appropriate.
1 mg = 1,000 mcg
1 mL = 1,000 µL
