Girls whose height is1.4m are generally 42.5kg-50kg, which is relatively normal.

Standard weight (male) = (height cm- 100)x0.9(kg), standard weight (female) = (height cm- 100)x0.9(kg)-2.5(kg), normal weight: standard weight+-(how much) 650. This is a formula commonly used in the world to calculate people's weight and body proportion.

Overweight: 65,438+00% above standard weight and 20% below standard weight. Mild obesity: 20% above standard weight and 30% below standard weight. Moderate obesity: 30% above standard weight and 50% below standard weight. Severe obesity: more than 50% of the standard weight. People who are underweight are thin.

Extended data:

Body mass index (BMI) is a number obtained by dividing the kilograms of weight by the square of the meters of height. It is a widely used international standard to measure the degree of obesity and health.

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. The National Institutes of Health (NIH) advises doctors to refer to the following three factors to assess whether a patient is overweight.

Body mass index waist circumference-measures the risk factors of abdominal fat and obesity-related diseases, such as hypertension, high LDL ("malignant") cholesterol, low HDL ("benign") cholesterol, hyperglycemia and smoking.

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. This is because children in different regions grow at different speeds, and it is easy to make wrong judgments if a fixed value is used.
