Educational math tool. This calculator only converts units (mg, mcg, mL, syringe units). It does not suggest amounts and is not medical advice. Always double-check your own math.

How the math works

Concentration = vial mg ÷ water mL.
10 mg ÷ 2 mL = 5 mg/mL = 5,000 mcg/mL

Volume = amount per draw ÷ concentration.
250 mcg ÷ 5,000 mcg/mL = 0.05 mL

Units on a U-100 syringe = mL × 100.
0.05 mL × 100 = 5 units
