Understanding BMI

The Body Mass Index is a simple index of weight‑to‑height that is commonly used to classify underweight, overweight, and obesity in adults. It is calculated as weight (kg) divided by the square of height (m). While BMI does not directly measure body fat, it correlates with more direct measures and provides a quick health screening tool.

Use this calculator to monitor your health trends over time. Remember that BMI is a population‑based metric; individual health assessments should consider other factors such as muscle mass, bone density, and overall fitness.
