Hello, I'm glad to answer your questions: adult: (height (cm)- 100] * 0.9 = standard weight (kg) and the other is: male: height (cm)- 105 = standard weight (kg), and female: height (cm)-650. In addition, the Academy of Military Sciences also introduced a method to calculate the ideal weight of China people: the ideal weight of northerners (kg) = (height cm- 150) x 0.6+50, and that of southerners (kg) = (height cm- 150) x 0.6+48. This calculation method seems to be more suitable for people in northern and southern China. Weight evaluation indicators are as follows: 60% below standard weight, severe malnutrition, 60-80% of standard weight, moderate malnutrition, 80-90% of standard weight, mild malnutrition, 90-10% of standard weight, and120 of normal range > standard weight.
