📌 Project Description

This simple Python program reads the distance between any two cities in Kilometers (Km) and automatically converts and displays it in meters (m), centimeters (cm), and miles.

🎯 Features

* Accepts user input for distance in Kilometers.

* Converts Kilometers into Meters, Centimeters, and Miles in real-time.

* Displays formatted output, including rounding the miles to two decimal places.

💻 Python Code

distance = int(input('Please Enter the distance(Km) between two cities:'))

meter = distance * 1000

centimeter = distance * 100000

miles = distance * 0.6213

print('Distance :', distance)

print(' Meter: ', meter)

print(' Centimeter: ', centimeter)

print(' Miles: %.2f' % (miles))

📊 Example Output

Please Enter the distance(Km) between two cities: 10

Distance : 10

 Meter:  10000

 Centimeter:  1000000

 Miles: 6.21

🧮 Calculation

* **Meters:** $\text{Meter} = \text{Distance in Km} \times 1000$

* **Centimeters:** $\text{Centimeter} = \text{Distance in Km} \times 100000$

* **Miles:** $\text{Miles} = \text{Distance in Km} \times 0.6213$

Example for 10 Km:

* $\text{Meter} = 10 \times 1000 = 10000$

* $\text{Centimeter} = 10 \times 100000 = 1000000$

* $\text{Miles} = 10 \times 0.6213 = 6.21$

🚀 How to Run

1. Install Python 3 on your local system.

2. Save the code into a Python file named `distance_converter.py`.

3. Open terminal or command prompt, navigate to the directory and run:

   ```bash

   python distance_converter.py

   ```

4. Enter the distance in Kilometers and view the converted values.
