What is BMI Calculator?
A BMI (Body Mass Index) calculator is a tool used to estimate a person’s body fat based on their height and weight. It provides a numerical value that categorizes an individual into different BMI ranges, which are associated with various levels of body fatness and potential health risks.
The BMI calculation formula is:
BMI = weight(kg) / (height(m))^2
The resulting BMI value is then compared to standard BMI categories to assess whether a person is underweight, normal weight, overweight, or obese. These categories provide a general indication of the person’s weight status and the potential health implications of their body composition.
It’s important to note that while BMI is a widely used indicator, it has limitations, as it doesn’t differentiate between muscle mass, bone density, and fat mass. Athletes and individuals with high muscle mass might have a higher BMI even though they have a healthy level of body fat. Therefore, BMI should be considered as one of several factors when evaluating a person’s overall health and well-being.
