Medication dosage by weight calculator

Calculate a reference medication dose from weight, mg/kg value, solution concentration, daily frequency and rounding rules with strict safety warnings.

Calculator settings

Use prescribed values onlyCopy the medicine name, mg/kg basis, frequency, concentration and maximum doses exactly from the prescription or official label. Recheck kg versus lb and mg versus ml; the calculator never chooses a dose or infers a safe maximum.

Result

Enter every prescribed value using the exact units shown. Weight, dosage, frequency and concentration must be positive numbers. Reference conversion only. Verify the medicine, concentration, dose basis, frequency, measuring device and maximum dose with the official label and a clinician or pharmacist before giving any medicine. Never treat units such as insulin units as mg or ml.

Reference mg/kg medication dose calculator

The calculator converts user-entered mg/kg dosing into single-dose and daily totals, then estimates liquid volume from concentration.

It does not recommend medicines, choose a dose or replace a clinician, pharmacist or official medicine label.
