Build BMI Calculator using Python

 Welcome to the Blog !! Today we will learn to build our own BMI (Body Mass Index) calculator which will help us to decide our BMI Category (Underweight ,  Normal Weight or  Overweight). 

✅ Problem Statement :

Mrs. Roy is very conscious about health and fitness. She regularly calculates BMI (Body Mass Index) in order to stay fit. But she hates calculations. So our job is to find simplify her task.

🔴 Formula to Calculate BMI :

      BMI = (weight)/(height*height)

🔴 BMI Categories :

1. Underweight - If BMI <=18.5
2. Normal Weight - If BMI is in between 18.6 - 24.9
3. Overweight - If BMI is >=25

✅ Concepts Covered in this Post :

• if..else statement
• input() function
• print() function
• round() function

📑Let's Code :)

Step 1 : Create new Python project and start writing code to build BMI Calculator.

We need to take 2 parameters as an input 

1. Weight (in kg)
2. Height (in cm)

To take input from user we will use input() function in python.

Step 2 : After taking input , we need to convert height in centimeter to meter.

So divide let's divide height(in cm) by 100. 

Calculate BMI using this formula :  BMI = (weight)/(height*height)

Refer below sample code for BMI Calculator :

bmiCalculator 1.1

Here we have used round() function to round off calculated BMI upto 2 decimals.

Step 3 : Let's run our code :)

Below is the sample output of the above code 👇👇
