THIS IS A VERY SIMPLE CALCULATION :
BMI= WEIGHT[KGS]/ HEIGHT[MTR] X HEIGHT[MTR]
NOW SUPPOSE SOMEONE'S WEIGHT = 56 KGS
HIS HEIGHT IS = 5'4" =64" =64X.0254=1.6256 X 1.6256= 2.6425
SO AS PER EXAMPLE =56 / 2.6425 =21.19
SO THE PERSON'S BMI STANDS TO 21.19
NOW GO TO THE FOLLOWING CHART :
BELOW 18.5 = UNDERWEIGHT
18.5 TO 24.9 = NORMAL
25.0 TO 29.9 = OVERWEIGHT
OVER 30 = OBESITY
