What Is a Body Mass Index?
A Body Mass Index (BMI) is a measurement that helps to assess an individual’s body fat based on their height and weight. This calculation is commonly used in South Africa to determine if a person is underweight, normal weight, overweight, or obese. For example, a BMI of less than 18.5 is considered underweight, while a BMI of 25 to 29.9 indicates overweight.
How to Calculate Body Mass Index Manually
The formula to calculate BMI is weight in kilograms divided by height in meters squared. Mathematically, it is expressed as BMI = weight (kg) / height^2 (m^2).
For example, if a person weighs 70 kilograms and stands 1.75 meters tall, their BMI would be calculated as follows:
BMI = 70 / (1.75 x 1.75)
BMI = 70 / 3.0625
BMI ≈ 22.85
