Reconstitution math, explained carefully
The calculation is a sequence of unit conversions. Each step depends on accurate values supplied by the user; none of the steps determines what dose or diluent is appropriate.
Start a calculation →Step 1: normalize the dose unit
If a confirmed dose is entered in micrograms, divide by 1,000 to express it in milligrams before combining it with a concentration expressed in mg/mL.
dose (mg) = dose (mcg) ÷ 1,000Step 2: calculate concentration
concentration (mg/mL) = vial amount (mg) ÷ liquid volume (mL)Step 3: calculate the draw volume
draw volume (mL) = confirmed dose (mg) ÷ concentration (mg/mL)Step 4: convert milliliters to a U-100 scale
Always compare the result with the original labels and instructions. Stop if any value, unit, concentration, or device marking is uncertain.
U-100 units = draw volume (mL) × 100Related VialPilot resources
