WARNINGS:
• Bmi measurement is a good indicator for the average person from 25 to 65 years of age. But there are limitations. Bmi calculation does not take into consideration muscle mass or your overall body type ( there are 'apple' and 'pear' of body types).
• Recent research has shown that the waist to hip ratio measurement is much more better than bmi to determine whether an individual has too much body fat. Generally the waist to hip ratio should not exceed about 0.9 for the average men and 0.8 for women. Higher ratios indicate higher risk of heart attack, stroke and diabetes.
• BMI SCALE:
Bmi less than 18 indicate underweight
Bmi of less than 18.5 indicate that you are thin for your health
Bmi of between 18.6 to 24.9 indicates you are at a healthy weight
Bmi of 25 to 29.9 indicates you are overweight for your health
Bmi of 30 indicates obesity

STEP BY STEP GUIDE ON HOW TO CALCULATE YOUR BMI
The basic formula for using BMI to calculate body weight is as follows:
Mathematically bmi = km/m2 ( kilometre per square. meter.
Bmi = ( body weight in kg)
( Body weight in meters)2. =
( Weight in kg)
Bmi formula = ( height in meters) * ( height in meters)
Example:
A person is 175 cm tall and has a weight of 70kg
Bmi =
70
1752
=
70
175*175
= 70
30625
= 22.66 ( normal weight)
Note that this is calculation using kilograms and health squared per meter.

• Take your height in inches and square the number
• Divide your weight in pounds with the result of your height in inches
• Multiply the answer with 703
The answer you get, is your body mass index.
