BMI

What is BMI?

The Body Mass Index (BMI) is a measurement tool that compares the individual’s height & weight to give an indication of whether he/ she is overweight, underweight or at a healthy weight for height. However this is general advice for adults only. It does not apply to children, pregnant women or women who are breastfeeding. Also your BMI may not be accurate if you are an athlete or a weight trainer, have a long term medical condition or are over the age of 60 years.

How is BMI calculated?

BMI is calculated by using one of the following equations:
BMI = ( Weight in pounds/ Height in inches x Height in inches.) x 703
OR
BMI= (Weight in kilograms/ Height in meters x Height in meters)

Steps

(The following formula is calculated in pounds and inches)
1. Collect a few household materials to find your Body Mass Index (BMI): your bathroom scale; a yardstick; a pencil and paper and calculator.
2. Weigh yourself on your bathroom scale.
3. Measure your height in inches using the yardstick.
4. Use the pencil, paper and calculator to perform the following BMI calculation.
5. Take your height in inches and square the number (i.e. multiply the number of inches by the same number of inches).
6. Divide your weight in pounds by the second figure (your height in inches, squared).
7. Multiply that answer by 703. The answer is your Body Mass Index.
Interpretation
Judge your personal BMI result against the following scale: A BMI of less than 18 means you are under weight. A BMI of less than 18.5 indicates you are thin for your height. A BMI between 18.6 and 24.9 indicates you are at a healthy weight. A BMI between 25 and 29.9 suggests
