Dose and Concentration to Volume

Dose:  mg
Concentration:  mg/mL
Based on the dose and concentration provided, the volume is:
Volume = Dose ÷ Concentration = ?

Volume and Concentration to Dose

Volume:  mL
Concentration:  mg/mL
Based on the volume and concentration provided, the dose is:
Dose = Volume × Concentration = ?

Notes

The following should be remembered when discussing and using injectables:

  1. Volume is meaningless without concentration (in terms of understanding dose).
  2. What is being used should generally be stated in terms of dose rather than volume. This is because concentration is also required for volume to be meaningful (#1 above) and because dose is much more readily interpretable to other people.
