Body Mass Index (BMI) is a simple calculation based on height and weight. It helps estimate whether a person's body weight falls within a common weight category.
BMI is widely used in fitness, healthcare, education, and personal health awareness. Although BMI does not directly measure body fat, it can provide a general indicator of weight balance.
BMI is calculated using the formula:
Weight (kg) ÷ Height² (m²)
The calculator automatically performs this formula and displays the result instantly.
BMI can help people understand whether their weight falls into a common health-related category. Many people use BMI calculators for fitness planning, diet awareness, and health tracking.
However, BMI should be considered a general estimate and not a complete medical diagnosis.
