Calculate Body Mass Index (BMI).

What is Body Mass Index (BMI)? Body Mass Index (BMI) is a statistical method to measure the weight of a person scaled according to height, to determine amount of body fat and it applied to both men and women.

The following are the BMI categories:

·         BMI value of less than 18.5 is refer to as Underweight

·         BMI value of between 18.5 and 24.5 is refer to as Normal weight

·         BMI value of between 25.0 and 29.5 is refer to as Over weight

·         BMI value of 30 and above is refer to as Obese

How BMI is calculated:

A: When measurement unit for weight is in kilograms (kg) and height is in meters:

Formula: weight (kg)/ [height (m)]2

Example: weight= 68kg, height= 165cm (1.65m)

Calculation: 68/ (1.65)2= 24.98

B: When measurement units for weight are in pound and height is in inches:

Formula: weight (lb)/ [height (in)]2*703

Example: weight = 150 lbs, height= 5’5” (65”)

Calculation: [150/ (65)2]* 703= 24.96
