What is the Body Mass Index Calculator & How does it work?
Body Mass Index (BMI) is a simple, widely used metric that relates a person’s weight to their height, providing a quick snapshot of whether they fall within a healthy weight range. The calculation yields a number that can be compared against standard categories—underweight, normal weight, overweight, and obesity—helping individuals and clinicians assess potential health risks associated with excess or insufficient body mass. While BMI is useful for population‑level screening, it does not account for muscle mass, bone density, or fat distribution, so it should be interpreted alongside other health indicators.
\text{BMI}=\frac{\text{weight,(kg)}}{\left(\text{height,(m)}\right)^2}
weight = body mass in kilograms
height = stature in meters
height = stature in meters
