Concentration calculator (mg/ml or IU/ml)
From amount of active ingredient and volume: mg/ml, µg/ml, percent and ratio 1:X
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.
Frequently asked questions
