Pharmacy Liquid and Solid Dilution Calculator
To dilute or change the strength of a concentrated preparation, adding a diluent to it is necessary which would result in the final preparation having a lower percent strength.
Dilution Calculator
Choose the unknown, then enter the three known values.
V₂ is the final total volume, including the stock solution. Enter both volumes in the selected volume unit and both strengths in the selected strength unit. Units are labels; values are not automatically converted. For percentages, both must use the same basis (e.g. % w/v). Assumes diluent contains none of the solute.
