Reverse tools

Work backwards from a volume, unit count, or click count to the amount of drug it represents — or find the diluent volume for a target concentration. All values are entered by you.

Arithmetic only

These tools convert numbers you enter. They do not recommend a dose, a concentration, or a device setting. Confirm every value with a licensed clinician or pharmacist.

Inputs

Final concentration (mg/mL)

Volume drawn (mL)

Enter a concentration and a volume to see the delivered dose.

Calculations use exact decimal arithmetic. Displayed numbers are rounded for readability only — they are not a measurement instruction. Measure only what a clinician or pharmacist has confirmed, using a device you have verified.
