About

This BMI calculator provides a quick and easy way to determine your Body Mass Index (BMI), a measure of body fat based on height and weight. The calculation is performed entirely client-side using JavaScript, ensuring immediate results and user privacy. The core formula for BMI is Weight (kg) / (Height (m))^2. For example, a person who is 175cm tall and weighs 70kg will have a BMI of 22.86 (70 / (1.75 * 1.75)), which is classified as 'Normal weight'. The calculator then categorizes this BMI into standard classifications such as Underweight, Normal weight, Overweight, or Obesity, providing a clear interpretation of the result.
