Mention the formula to calculate the BMI (Body Mass Index).

BMI (Body Mass Index):

1. Body Mass Index is a method of measuring through which individuals are classified into the following categories: obese, overweight, normal weight and underweight.
2. It is the proportion of your weight to the square of your height.
3. When a person's height and weight are given in inches and pounds, the BMI can be computed using the formula$\mathrm{BMI}=\frac{\mathrm{Weight}(\mathrm{in}\mathrm{pounds})}{\mathrm{Height}{(\mathrm{In}\mathrm{inches})}^2}\times 703$
   703 is a conversion factor in this case.
4. If the person's height and weight are supplied in meters and kilograms, the BMI can be computed using the formula :$\mathrm{BMI}=\frac{\mathrm{Weight}\left(\mathrm{kg}\right)}{\mathrm{Height}{\left(\mathrm{m}\right)}^2}$
