What is a BMI Calculator?

What is a BMI Calculator and Its Purpose?

A BMI (Body Mass Index) Calculator is an application that computes an individual’s BMI given their weight and height. BMI itself is defined as a person’s weight (in kilograms) divided by the square of their height (in meters).

This value is used as a simple health indicator: it categorizes individuals into ranges like underweight, normal weight, overweight, or obese based on standard BMI ranges. The purpose of a BMI calculator is to provide a quick, easy screening of whether someone’s body weight is in a healthy range. Our React-based BMI Calculator will feature input fields for weight and height and a button to calculate BMI.

Once the user inputs their data and clicks Calculate, the app will display the calculated BMI value along with the weight status category (e.g., Underweight, Normal, Overweight, or Obese).
