How to calculate the ratio of height to weight, and how to calculate the ratio of height to weight

Standard weight and obesity.

People are fat and thin, if they are too light, they are thin, and if they are too heavy, they are fat, so what is the standard to measure whether they are fat or thin? Of course, there must be a reference value, and this reference value, we call it the standard weight. At present, there is no unified standard weight data in China.

There are two most commonly used calculation methods:

One is: Adult: (Height (cm) - 100 0 9= Standard weight (kg) The other is:

Male: height (cm) 105= standard weight (kg), female: height (cm) 100= standard weight (kg) The above two calculation methods have basically been widely used.

In addition, the Academy of Military Sciences has also introduced a method for calculating the ideal weight of Chinese:

The ideal weight (kg) (height cm 150) x 0 6 50 for northerners and the ideal weight (kg) (height cm 150) x 0 6 48 for southerners seems to be more suitable for Chinese in the north and south. The easy way to calculate the standard weight of a child is: 1 to 6 months:

Birth weight (kg) 10 years old Standard weight (kg); 7 12 months: birth weight (kg) 10 years of age x 0 5= standard weight (kg); Over 1 year: 8 ten years of age x 2 = standard weight (kg).

However, because people's weight is related to many factors, there are differences between different human bodies, and there will be certain changes at different times on the same day, coupled with the geographical location (such as gravity), season, climate, and their own conditions, which also have a certain impact on weight, so it is difficult to fully meet the standard weight. That is to say, it is difficult to express it with a constant value, but it should be a numerical range, which we call the normal value, which is generally within the range of standard weight +-10. Exceeding this range is referred to as an abnormal weight.

Those who have a measured weight that exceeds the standard body weight, but exceed the part by 20 are called overweight; Obesity can be diagnosed if the measured weight exceeds the standard weight by more than 20 and the fat percentage (f) exceeds 30. Those who weigh more than 30 to 50 of the standard body weight, and those who exceed 35 to 45 are called moderate obesity; Those who exceed the standard body weight by 50 or more, and F who exceed 45 or more, are called severe obesity.

There is a very simple way, regardless of gender.

a = weight (kilograms) and the square of the height (in meters) is enough.

If a<18 is thin;

If 1824 is on the fat side;

If a>26 is overweight;

It doesn't matter if the error is within 10%.

So your standard weight should be between kilograms.

2 (height - 105) This is the standard weight.

For example, if you are 160cm tall, the standard weight is.

2 (160-105) = 110 catties.

Height minus 100 is the standard weight.

Weight (kg) divided by height (m) squared.

Between 18 and 24 is the standard.

For example, a certain child is 1.5 meters tall and weighs 45 kilograms.

The ratio is 45 (

It belongs to the standard body of construction.

Body mass index (kg of travel) divided by the square of height (m) kg m2. It is generally considered that the normal BMI is between 18 and 25, the BMI between 25 and 30 for overweight, and above 30 for obese.

1. Normal weight: body mass index 18-25.

2. Overweight: body mass index 25-30.

3. Mild obesity: body mass index 30.

4. Moderate obesity: body mass index 35.

5. Severe obesity: body mass index 40.

Height and circumference index

Height Bust Index (Bust Height) 100: Asian male average, Asian female average; The average for European and American men is for European and American women.

Height waist circumference index (waist circumference height) 100: Asian male average, Asian female average is; The average for European and American men is for European and American women.

Height-hip index (hip height) 100: Asian male average, Asian female average; The average male in Ou Jing Town is average, and the average for European and American women is.

1. First of all, the common calculation method for calculating the proportion of weight and height, the standard weight for women = height-105, and the standard weight for men = height 100. The common calculation method for calculating the weight and height ratio is: body mass index = weight (kg) and height (m) squared.

The ideal body mass index is 22.

2. It is generally believed that the normal body mass index is between 18 and 25, the body mass index of overweight is between 25 and 30, and the body mass index of obesity is above 30. When this body mass index, which describes the ratio of height to weight, is the same, it means that the woman has the most mega figure.

3. However, because people's weight is related to many factors, there are differences between different human bodies, and there will be certain changes at different times on the same day, coupled with the geographical location (such as gravity), season, climate, and different conditions of their own situation, which also has a certain impact on body weight, so it is difficult to fully meet the standard weight.

Weight (kg) divided by height (m) squared Between 18 and 24 For example, a child is 1.5 meters tall and weighs 45 kg. The ratio of 45 ( =45 =20 belongs to the standard stature.

Hello dear, the calculation of the height and weight ratio refers to the calculation of the standard weight of a person of this height according to the height of the person through a certain method. The World Health Organization formula is: (height in centimeters - 80) and the formula for women is:

height in centimeters - 70). It is considered normal within the upper and lower 10% of the calculated body weight. In fact, everyone's body shape has certain individual differences, and this calculation method is not completely suitable.

Weight in kilograms divided by height in meters squared.

Between 18 and 24 is the standard.

For example, a child is 1.5 meters tall and weighs 45 kilograms.

The ratio is 45 (

20 belongs to the standard body.

A height of -105 is equal to the standard weight.
