Estimate a single milligram dose as weight × mg/kg, capped at a stated maximum.
| Dose (mg) | – |
Use this calculator for dose = min(weight × mg/kg, max mg). Paracetamol, ibuprofen, amoxicillin, and similar monograph pages are this identity with different mg/kg. Confirm the labelled product and the monograph. This is not a substitute for a marked oral syringe and not a multi-dose daily total.
Weight can be entered in kilograms (kg) or pounds (lb); the calculator converts to kilograms before the formula.
Weight: Child’s body weight, in kg or lb.
mg / kg: Milligrams per kilogram, for example 15 mg/kg paracetamol.
Max (mg): Ceiling so the calculated dose cannot exceed the adult-style cap you type.
Dose (mg): Single dose in milligrams of active ingredient.
