Introduction

The Body Mass Index (BMI) is a common measure of body fat based on one's height and weight.

For this calculator, we intepretate the results based on the explanation given by the US Centres for Disease Control and Prevention.

  • BMI < 18.5 = Underweight
  • BMI 18.5 to 25.0 = Normal
  • BMI 25.0 to 30.0 = Overweight
  • BMI > 30.0 = Obese

BMI Calculation

  • BMI = Weight (kg)/ Height(m)2 , or
  • BMI = Weight (lb) * 703 / Height (in)2

For example, if one is 1.80m and 75kg, his BMI would be

[1] 23.14815

Therefore, he is 

[1] "Normal"
