A BMI calculator helps in calculating Body-Mass Index.

Body Mass Index is a tool or a formula which helps us in knowing whether a person’s body weight is appropriate or not. It measures body weight with respect to the person’s height.

BMI is calculated by dividing a person’s weight in kilograms by square of height in meters.

BMI basically gives an estimate on how healthy our weight is.

According to National Institutes of Health (NIH):

A person with:

  • BMI less than 18.5 is considered underweight.

  • BMI between 25 and 29.9 is considered overweight.
