A BMI calculator helps in calculating Body-Mass Index.
Body Mass Index is a tool or a formula which helps us in knowing whether a person’s body weight is appropriate or not. It measures body weight with respect to the person’s height.
BMI is calculated by dividing a person’s weight in kilograms by square of height in meters.
BMI basically gives an estimate on how healthy our weight is.
According to National Institutes of Health (NIH):
A person with:
- BMI less than 18.5 is considered underweight.
- BMI between 18.5 and 24.9 is considered ideal.
- BMI between 25 and 29.9 is considered overweight.
- BMI above 30 is considered obese.

import java.util.Scanner; public class BMI{ public static void main(String args[]) { Scanner sc = new Scanner(System.in); System.out.print("Enter the weight in kilograms: "); double weight = sc.nextDouble(); System.out.print("\nEnter the height in meters: "); double height = sc.nextDouble(); double BMI = weight / ( height*height ); System.out.print("\nThe Body Mass Index (BMI) is " + BMI + " kg/m2"); } } |
Output:
Enter weight in kilograms: 55
Enter height in meters: 1.6
The Body Mass Index (BMI) is 21.484375 kg/m2
