About this calculator
The Pediatric Dose Calculator is a practical tool to estimate medication doses based on the child's weight and the recommended dosage per kilogram. Simply enter the weight in kg and the dosage in mg/kg to get the total dose. The formula used is: dose = weight × mg/kg.
This calculator is useful for parents, caregivers, and healthcare professionals who need to quickly calculate the correct amount of medication for children. Examples include antipyretics, antibiotics, and other pediatric medicines. Remember: the tool is only an aid and does not replace medical evaluation.
Important precautions: always verify the dosage with a medical prescription or pharmacist. Weight should be up-to-date, especially for younger children. The calculator assumes the mg/kg dosage is correct; input errors can lead to underdosing or overdosing. Use responsibly.
Frequently asked questions
Does the calculator replace a medical prescription?
No. The calculator is only a support tool. Always confirm the dose with a doctor or pharmacist before administering any medication.
What if the child weighs less than 5 kg?
The calculator works for any weight, but for very small infants, dosing must be extremely precise and supervised by a professional.
Can I use it for liquid medications?
Yes, as long as you have the correct concentration. The calculator gives the total dose in mg; you will need to convert to ml according to the label.
What if the calculated dose seems too high?
Double-check the input. If correct, consult a doctor before administering. Never exceed the maximum recommended dose.
Does the calculator store data?
No. Calculations are done locally in the browser, and no data is saved or shared.
