Body
mass index or BMI, is a new term to measure or
study obesity. It provides a reliable indicator
of body fatness for most people. BMI uses a mathematical
formula that takes into accounts both a person's
height and weight. BMI equals a person's weight
in kilograms divided by height in meters squared.
(BMI= Weight in
kg / height in meter square).
Or divide weight (in Kg) by height (in meters)
and divide the result again by height (in meters)
of the person.

Calculate
your BMI
BMI can be determined by dividing your
weight in pounds by your height in inches squared
and then multiplying by 705.
For example, a
person who is 5 feet 8 inches and weighs 180
Lbs would have a BMI of 27
• Height = 68 inches
• 68 squared = 4624
.Weight =180 Lbs
• 180 divided by 4624= 0.0389
• 0.0389 x 705 = 27.42 (rounded up to
BMI of 27)
Charts and calculators to determine your BMI
are easily found on most health and diet websites.
