For example: 70kg (1.75x1.75) = 22.86.
For example:
For example, a person's height is 1.75m and his weight is 68kg, and his body mass index = 68/( 1.75 2) = 22.2 (kg/m 2). When the body mass index is 18.5 ~ 23.9, it is normal.
Body mass index was originally designed as a statistical tool for public health research. When we need to know whether obesity is the cause of the disease, we can convert the patient's height and weight into body mass index, and then find out whether there is a linear correlation between this value and the incidence. However, with the development of science and technology, the current body mass index value is only a reference value.
Extended data adult body mass index value:
Too light: less than 18.5
Normal: 18.5-23.9
Overweight: 24-27 years old
Obesity: 28-32 years old
Very obese, over 32 years old.
Because of the error, the body mass index can only be used as one of many standards to evaluate the individual's weight and health status.

standard
Traditionally, the weight standard for adults is below 30, but the Asian adult index has recently been changed to 27.5. Asian adults with a body mass index of 24 are considered overweight, while the ideal index is 18.5 to 23.9.
Children's body mass index values are not only applicable to adults. For growing children, we can also use their body mass index to calculate whether they are overweight. The above formula for calculating body mass index is also applicable to people aged 2-20, but their overweight and body mass index are not determined by a fixed body mass index value.
