⚠️ Important Disclaimer

This tool performs only a simple weight-based multiplication. The results are for reference and educational purposes only and do not constitute medical advice. Actual medication for children, pregnant women, and pets must be determined by a physician or veterinarian based on the specific condition, age, liver and kidney function, and other factors. An incorrect dose can be life-threatening — never administer medication based solely on this tool.

How to use

mg/kg means “milligrams per kilogram of body weight per dose”. Take this value from the drug's package insert or the prescription: inserts usually state “X mg/kg per dose” or “X mg/kg per day divided into N doses”; if a daily amount is given, divide it by the number of daily doses before entering it here.

Formulas: dose per administration (mg) = weight (kg) × dose per kg (mg/kg); daily total (mg) = dose per administration × doses per day.
