Read the scale carefully
The bar shows where the calculated number falls on a U-100 syringe scale. On this scale, 100 units means 1 mL. Smaller U-100 syringes may stop at 30 or 50 units. Check the markings on your actual syringe.
See every step.
Enter the mg in your vial, the total mixed liquid in mL, and the dose you want to calculate. See how they turn into mL and U-100 syringe units. This shows the math; it does not choose a dose.
01 / mg in each mL—mg in vial ÷ mixed mL
02 / Liquid for your dose—your dose ÷ mg in each mL
03 / U-100 syringe units—liquid mL × 100
Enter positive values to see the conversion.
