About BMI Calculator
A BMI calculator is a simple health utility that estimates body mass index using weight and height. It helps users understand whether their weight falls into underweight, normal, overweight or obese ranges.
BMI is useful for general awareness, fitness planning and health tracking. It should not replace professional medical advice, but it is a quick starting point for understanding body weight status.
