Want to know if your weight is OK? It’s easy. Here’s how: First, measure your height and weight.
Then devide your weight in kilograms by your height in metres squared. That is: your own weight (in kilograms)÷your height(in metres) Let’s look at a boy as an example: Height: 1.55metres; Weight: 70 kilograms 1.55×1.55=2.470÷2.4=29.17 Check with the table below, for people from 2 to 19. You’ll find that he is heavy. Maybe he has to turn to the story at the bottom to get some advice. What about your own result? Check the table. Are you OK? 不要翻译器翻译,谢谢
