Calculation steps: Take centimeters (cm) as the unit, measure the height with a ruler or measuring tool to ensure the accuracy of the height. Take kilograms (kg) as the unit, and measure the weight with scales or scales to ensure the accuracy of the weight. Convert the unit of height from centimeter (cm) to meter (m), that is, height (cm)/ 100. Divide the weight (kg) by the square of the height (m) to get the body mass index value.
For example, the height 170cm (1.70m) and the weight are 65kg. The calculation process is as follows: body mass index = 65/(1.70 *1.70) = 22.5 According to the calculation results, the body mass index is 22.5. According to different ranges of body mass index, we can preliminarily judge a person's weight and health status: body mass index.
It should be noted that the body mass index (BMI) is only a preliminary weight evaluation index, and it cannot completely and accurately judge a person's health status.
Factors affecting body mass index:
1, weight: weight is the main factor in calculating body mass index. Being underweight or overweight will affect the body mass index.
2. Height: Height is also an important factor in calculating body mass index. A taller person can have a higher weight, but still maintain a healthy body mass index.
3. Age: Generally speaking, the body mass index will increase slightly with age.
4. Gender: Men and women have different body fat distribution and muscle ratio, so gender may have some influence on body mass index.
5. Bone structure: Different people's bone structure may also have a certain impact on body mass index. For example, some people have a heavy bone structure and may have a relatively high body mass index.
6. Muscle content: Muscle is heavier than fat, so people with high muscle content may have a higher body mass index, even if they are not obese.
