Estimate a liquid medicine dose in ml from a child's weight.
Pediatric liquid doses scale with body weight: the child's weight in kilograms times the milligrams-per-kilogram dose gives the milligrams, then dividing by the concentration yields the milliliters to measure out. A common maximum is four doses per day. Accidental overdose is a real risk when parents use teaspoons or guess, so a weight-based ml calculation prevents both underdosing and overdosing.
Pediatric Dosage by Weight
Dose ml = weight x mg per kg / concentration (mg per ml)
