What Is a BMI Calculator?
A Body Mass Index (BMI) calculator is a tool used to estimate the amount of body fat based on an individual’s weight and height. It is commonly used by healthcare professionals to assess a person’s risk for certain health conditions related to weight. In South Africa, it can be helpful for individuals who want to monitor their weight and overall health.
How to Calculate BMI Manually
The formula for calculating 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 is 1.75 meters tall, the calculation would be BMI = 70 / (1.75 x 1.75) = 22.86. This value falls within the healthy weight range.
