What is BMI?
Body Mass Index (BMI) is a simple measurement that compares your weight to your height. It helps estimate whether your body weight falls within a healthy range. BMI is widely used as a screening tool, but it does not directly measure body fat or overall health
📐 BMI Formula
How BMI is Calculated
BMI = Weight (kg) ÷ Height² (m²)
BMI is calculated by dividing your weight in kilograms by the square of your height in meters. The result helps classify whether you are underweight, at a healthy weight, overweight, or obese.
