Pediatric dosing is typically calculated based on the child's weight in kilograms (kg). The formula often used is:
Dose (mg) = Dose per kilogram (mg/kg) x Weight (kg)
In some cases, dosing may also be based on body surface area (BSA), especially for certain medications like chemotherapy agents. The formula for BSA is:
BSA (m²) = √[(Height in cm x Weight in kg) / 3600]
