Dosage converter
Convert a dose per kilogram into the total dose for a body weight, or back again. Pick the weight first: everything below follows from it.
That's 1.5× as strong as a standard dose, while a high dose is 2× higher. Information only: always follow the prescription or the label.
What it means
How much is that in total?
Information only, not medical advice. Never dose from a converter: follow the prescription or the label, which accounts for age, kidney function and the medicine itself.

Three things worth knowing
-
Total = mg/kg × body weight
A 15 mg/kg dose for a 25 kg child is 375 mg. The arithmetic is simple, which is exactly why a slip in it is so dangerous.
-
Why children are not small adults
Children clear drugs at different rates, not just in smaller amounts. Per-kilogram dosing is a first approximation that pediatric guidelines then adjust.
-
Pounds and kilograms
Reading a weight in pounds as kilograms more than doubles the dose. It is one of the most common medication errors on record, which is why hospitals weigh in kilograms only.

Background
About dosing by weight
Many medicines are prescribed per kilogram of body weight, especially for children, where one adult dose would be far too much. Turning that into an actual amount needs the patient’s weight, which is the setting above.
