Medication Dosage Calculator (mg/kg)
Weight-based dose calculator: total mg from mg/kg and patient weight, plus volume to draw from a concentration. Education/reference only.
For Reference & Education Only. Not for Real-world Clinical Use.
This calculator is a study and teaching aid. Do NOTuse it to make real patient care, dosing or treatment decisions. Always confirm every value against a licensed clinician, your institution's approved protocols, the drug label and a validated clinical reference. No warranty of accuracy is given, and no liability is accepted for any use.
Total dose = dose per kg × weight (kg). Volume = total dose ÷ concentration.
What Is the Medication Dosage Calculator (mg/kg)?
The Medication Dosage Calculator computes a weight-based dose: enter the dose in mg per kg and the patient's weight (kg or lb) to get the total milligrams, and optionally a drug concentration in mg/mL to get the volume to draw up. This is a reference and education tool only and must not be used for real-world clinical decisions — always confirm with a licensed clinician, the drug label and your institution's approved protocols.
How It Works
Enter the mg/kg dose and the patient weight; add a concentration to also get the volume in mL. Results update instantly.
When to Use It
As a study aid for learning weight-based dosing. Never for real dosing decisions — confirm every dose with a clinician, pharmacist, the label and your protocols.
Frequently Asked Questions
- How is the dose calculated?
- Total dose = dose per kg × weight in kg. Volume to give = total dose ÷ concentration. Pounds are converted to kg automatically.
- Is this safe for real use?
- No — it is an educational reference only. Dosing must always be verified by a licensed professional against approved sources.
