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 the degree of 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.
