Weight standard calculation formula, fitness people often calculate their weight standard to see if their weight is within the standard value, but there are still many people who don't know how to calculate their weight standard. Below I sorted out the formula for calculating the weight standard.
Weight standard calculation formula1i. WHO calculation method:
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 = square kilogram of body weight/square meter (kilogram)/height (meter)
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. Formulas for China people divided 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.
Weight standard calculation formula 2 Male standard weight calculation formula = (height cm- 100)x0.9(kg)
Formula for calculating female standard weight = (height cm- 100)x0.9 (kg) -2.5 (kg)
Normal weight: standard weight+-(how much) 10%
Overweight: greater than the standard weight 10%, less than the standard weight by 20%.
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 standard weight.
Weight standard calculation formula 3 The standard weight is equal to the height minus 1 10. For example, the height 160cm, the standard weight should be 160 minus10 equals 50kg.
People who exceed the standard weight 10% are overweight, those who exceed the standard weight 20% are obese, those who are below 10% are emaciated, and those who are below 20% are emaciated. In addition, there is another calculation method, that is, using the body mass index, which is the standard calculation formula of WHO.
Body mass index is equal to weight divided by the square of height, and the body mass index of standard weight is 18-24. You can use this formula to calculate your standard weight by height. The allowable calculation error is about 10%. Take a woman with a height of 160 as an example. Her standard weight should be 54kg.
The standard weight is introduced as follows:
If the weight is between 48.6 and 59.4 kilograms, it is normal. China Yangtze River is the main division, taking into account the influence of regional factors on body weight. The standard weight of Jiangnan women = (height-150) × 0.6+48; The standard weight of women in the north of the Yangtze River = (height-150)×0.6+50.
According to this formula, people who weigh more than 30% of the standard weight are considered moderately obese. Similarly, taking 160 women as an example, the standard weight south of the Yangtze River is 54 kg, and reaching 70.2 kg is considered as moderate obesity.
