A: This formula provides a rough estimate and may vary from actual weight by ±20%. It's most accurate for children aged 1-10 years.

Q2: When should this formula be used?
A: Primarily in emergency situations when actual weight measurement is not possible for medication dosing or equipment selection.

Q3: Are there other pediatric weight estimation formulas?
A: Yes, other formulas include the Advanced Pediatric Life Support (APLS) formula and the Broselow tape system which uses height to estimate weight.

Q4: Does this formula work for all age groups?
A: This formula is designed for children aged 1-18 years, but is most accurate for children between 1-10 years old.

Q5: Should this formula replace actual weight measurement?
