BMI (Body Mass Index) is a widely used health measurement that evaluates whether a person’s body weight is appropriate for their height. It provides a simple numeric value that classifies individuals into different weight categories.
BMI Formula:
BMI = Weight (kg) ÷ Height (m)²
Although BMI does not directly measure body fat percentage, it is a reliable screening tool used by doctors, fitness experts, and healthcare organizations worldwide.
Regular BMI checks can help prevent health conditions such as heart disease, diabetes, and high blood pressure, especially if your BMI falls in the overweight or obese range.
