Method for calculating standard weight in children

The formula for calculating the standard weight of children is: standard weight (kg) = age (years) × 2 + 8. This formula applies to children aged 2 to 12 years. According to this formula, the standard weight for a 2-year-old child is approximately 12 kg, for a 3-year-old child approximately 14 kg, and so on. Additionally, a child's weight gain is influenced by various factors such as genetics, nutrition, and living environment, and each child's growth and development may differ.
