Calculation reference

How the measurement is calculated

Enter the labelled vial amount and the total liquid volume. The calculator converts those values into concentration, material per U-100 unit and the volume represented by the target amount.

Units used

  • 1 milligram (mg) = 1,000 micrograms (mcg).
  • 1 millilitre (mL) = 100 U-100 units.
  • A 30-, 50- or 100-unit U-100 syringe changes capacity, not the value of one unit.

Formula sequence

  1. Convert the labelled vial amount to the target unit.
  2. Divide total material by total liquid volume to find concentration.
  3. Divide concentration per mL by 100 to find material per U-100 unit.
  4. Divide the target amount by material per unit to find the draw reference.

Worked example: 10mg in 2mL

This example uses the calculator's starting values and a mathematical target of 250mcg.

10mg × 1,000 = 10,000mcg total 10,000mcg ÷ 2mL = 5,000mcg/mL 5,000mcg/mL ÷ 100 = 50mcg per U-100 unit 250mcg ÷ 50mcg = 5 units (0.05mL) 10,000mcg ÷ 250mcg = 40 theoretical portions
