Dilution calculator
C1 × V1 = C2 × V2 – stock solution and diluent for a target concentration
Scientific basis
Control
Dose calculations for children are error-prone (decimal point errors, units, confusion of mg and ml). The calculated amount must be checked against the prescribing information or hospital standard and the maximum dose; the calculation line makes cross-checking easier.
Calculation aid for healthcare professionals: the calculator reproduces what the sources cited assign to the inputs. Clinical assessment and every treatment decision remain with the treating physician. Inputs and results are not stored.
