When rounding this result to two decimal places, it becomes approximately 20.41 kg. This aligns perfectly with the correct answer choice, indicating that the conversion was performed accurately according to the standard measurement conversions.

The importance of understanding this conversion lies in the necessity for healthcare professionals to accurately interpret and convert weights to ensure proper dosage and treatment regimens, particularly in pediatrics, where weight-based calculations are crucial.
