Simple BMI Calculator

A BMI calculator, also known as a Body Mass Index calculator, is a tool used to estimate an individual’s body mass index (BMI). BMI is a numerical value that is derived from a person’s weight and height and is commonly used to assess whether someone falls into a healthy weight range or not.

To calculate BMI, the formula used is:
BMI = weight (in kilograms) / (height (in meters))^2
The resulting BMI value can be interpreted to determine whether an individual is underweight, normal weight, overweight, or obese. Here are the commonly accepted BMI categories:

Underweight: BMI less than 18.5
Normal weight: BMI between 18.5 and 24.9
Overweight: BMI between 25 and 29.9
Obese: BMI of 30 or higher
