BMI Calculator

Body Mass Index (BMI) is a measurement of a person’s weight with respect to his or her height. It is more of an indicator than a direct measurement of a person’s total body fat.
BMI, more often than not, correlates with total body fat. This means that as the BMI score increases, so does a person’s total body fat.
The WHO defines an adult who has a BMI between 25 and 29.9 as overweight - an adult who has a BMI of 30 or higher is considered obese - a BMI below 18.5 is considered underweight, and between 18.5 to 24.9 a healthy weight .
BMI calculation
BMI in an individual is calculated by the use of a mathematical formula. It can also be estimated using tables in which one can match height in inches to weight in pounds to estimate BMI. There are convenient calculators available on internet sites that help calculate BMI as well.
The formula is - BMI = (Weight in kilograms) divided by (Height in metres squared)
A normal BMI score is one that falls between 18.5 and 24.9. This indicates that a person is within the normal weight range for his or her height. A BMI chart is used to categorize a person as underweight, normal, overweight, or obese.
