• Normal weight = 18.5-24.9
• Overweight = 25-29.9
• Obesity = BMI of 30 or greater

Example of calculation BMI Metric

Here we run the R code (in this case a mathematical formula) of the BMI Calculation for a person 1.60 meters tall and 60 kilograms:

BMIMetric = 60 / (1.6^2)
BMIMetric

[1] 23.44

As we can see the BMI is 23.44 which means that the person is in his/her normal weight.

Example of calculation BMI English Metric

Here we run the R code (another mathematical formula) of the BMI Calculation for a person 63 inches tall and 140 pounds in weight:

BMIEnglishMetric = 140 / (63^2) * 703
BMIEnglishMetric

[1] 24.8
