TB-500 Calculator
Enter the amount printed on your vial and the volume of liquid you use. The calculator shows concentration, volume and syringe units. It does the arithmetic only. It does not say how much of anything to use.

How the numbers work
Concentration = vial amount ÷ solution volume. Volume = target amount ÷ concentration. Units on a U-100 syringe = mL × 100. 1 mg = 1000 mcg.
Worked example (mathematical example only, not a recommendation): a vial labelled 10 mg in 4 mL is 2.5 mg/mL, or 2500 mcg/mL. A target of 500 mcg is 500 ÷ 2500 = 0.2 mL, which is 20 units.
Always use the amount and units printed on your own vial, and check them twice. Mixing up mg and mcg changes a result by a factor of 1000.
