At present, we all use the body mass index to calculate the standard weight, and the body mass index is also a commonly used international standard to measure the degree of obesity and health. There is a range of body mass index. If the body mass index is less than 18, the body weight is light. The normal value is 18-24, 24-28 is overweight, and above 28 is obese.
The formula for calculating the body mass index is as follows: the body mass index is equal to the weight per kilogram divided by the square of height. According to this formula, if the height is 1.65 meters, the standard weight is between 49 and 65 kg.

Body mass index can also judge whether the body is fat or thin. In China, the body mass index is within 18.5, that is, the body is thin. 18.5-23.9 belongs to normal weight, 24-26.9 belongs to overweight weight, 27-29.9 belongs to obese weight, and over 30 years old belongs to severe obesity. Even if the female is 165cm and weighs 57kg, the body mass index can be measured. This formula can be used, that is, weight/(height * height), that is, 57/(1.65 *1.65) = 20.94, which shows that the body mass index is within the normal weight range.
