Male: (height cm-80) × 70% = standard weight.
Female: (height cm-70) × 60% = standard weight.
Standard weight plus or minus 10% is normal weight.
Standard weight plus or minus 10 ~ 20% overweight or underweight.
Obesity or underweight is defined as plus or minus 20% of standard weight.
Overweight calculation formula
Overweight% = [(actual weight-ideal weight)/(ideal weight) ]× 100%
Second, the age algorithm is different.
Standard weight method
Standard weight (kg) = age x 8+8 (7- 16 years old)
Mild obesity: 20%-30% overweight.
Moderate obesity: 30%-50% overweight.
Severe obesity: more than 50% of standard weight.
Body mass index method
The square of body mass index = weight (kg)/ height (m) is kg/m2.
Age body mass index value
Normal age, overweight, mild obesity, moderate obesity and severe obesity.

Third, the simple calculation method
1, calculation method 1:
Body mass index = weight square kg/square meter (kg)/height (m)?
Formula writing: body mass index = weight/(height) 2
Normal weight: body mass index = 18.5-25 (China physical health standard: normal range: 18.5~23.9, overweight 24.0~27.9, obesity ≥28.0).
Overweight: body mass index = 25-30.
Mild obesity: body mass index >; 30
Moderate obesity: body mass index >; 35
Severe obesity: body mass index >; 40
2, calculation method 2:
Standard weight = height (m) × height (m) × standard coefficient (female 20, male 22)
Standard weight plus or minus 10% is normal weight.
Standard weight plus or minus 10 ~ 20% overweight or underweight.
Obesity or underweight is defined as plus or minus 20% of standard weight.
3, calculation method 3:
Standard weight (kg) = height (cm)-105
For example, a man with a height of 170cm should weigh170 (cm)-105 = 65 (kg). Those who exceed the standard weight 10% are overweight, and those who exceed 20% are obese; Under 0/0% of standard weight/kloc, those below 20% are thin.
Note: The above calculation method is only applicable to adults. Not suitable for children, old people or people who are too short.
4, Blocker formula:
Height 165cm or less: standard weight (kg)= height (cm)- 100.
Height1over 65cm: standard weight (kg)= height (cm)- 1 10.
5. Weight calculation formula applicable to Asian standards:
Professor Gui of Kyoto University put forward the following calculation formula on the basis of Blocker formula:
Standard weight (kg) = [height (cm)-100]×0.9.
Note: The calculation result of this formula is suitable for the specific situation of Asians.
6. Formula for China people to divide by north and south regions:
The ideal weight of northerners (kg)=[ height (cm)-150] × 0.6+50;
The ideal weight of southerners (kg)=[ height (cm)- 150]×0.6+48.
Extended data:
Standard weight is one of the important signs to reflect and measure a person's health. Being too fat and too thin is not good for your health, nor will it give you a sense of bodybuilding. A large number of statistical data of different body types show that the ideal and simple index reflecting normal weight can be expressed by the relationship between height and weight.
Body Mass Index (in English) is a number obtained by dividing the weight in kilograms by the square of the height in meters, and it is a commonly used international standard to measure obesity and health. When we need to compare and analyze the influence of a person's weight on the health of people of different heights, the body mass index is a neutral and reliable indicator.
