Reference: CCP_L01_C05_Unit Converter
📌 Introduction
Unit conversions are an essential part of
daily life, from converting Celsius to
Fahrenheit to Kilograms to Pounds.
If you're learning C programming,
building a Unit Converter in C is a
great hands-on project to strengthen your coding skills.
In this blog post, we will walk through
creating a menu-driven Unit Converter in
C, which allows users to convert values between different units and even
stores conversion history for future reference.
Let’s get started! 🚀
💡 Project Overview
This Unit
Converter in C
supports conversions for:
✔ Temperature (Celsius ↔ Fahrenheit)
✔ Mass
(Kilograms ↔ Pounds)
✔ Length
(Meters ↔ Feet)
✔ Time
(Minutes ↔ Seconds)
✔ View Conversion History (Saves
conversions in conversion_history.txt)
The program follows a menu-driven approach, making it
user-friendly and easy to interact with.
🔧 Features &
Enhancements
✅
Simple Menu
Interface
– Easy navigation for users.
✅ Multiple Unit Categories – Supports key unit conversions.
✅ View Conversion History – Stores past conversions in a file.
✅ Error Handling – Detects invalid inputs and handles errors gracefully.
✅ Modular Functions – Each
conversion type has its own function.
🛠️ Setting Up &
Running the Project
Step 1: Install
Code::Blocks IDE
Ensure you have Code::Blocks IDE with MinGW C Compiler installed.
Step 2: Create a New C
File
●
Open Code::Blocks.
●
Create a new file named unit_converter.c.
●
Copy and paste the Unit Converter C Code.
Step 3: Compile and Run
the Code
●
Click Build → Build and
Run or press F9.
●
The main menu appears:
===== UNIT CONVERTER =====
1. Temperature
2. Mass
3. Length
4. Time
5. View Conversion History
0. Exit
Enter your choice (1-5) or 0 to Exit:
📝 Example Run
💡
Converting Celsius to Fahrenheit
Select conversion:
1. Celsius to Fahrenheit
2. Fahrenheit to Celsius
Enter choice: 1
Enter value: 25
25.00 Celsius = 77.00 Fahrenheit
✅
The result is saved
in conversion_history.txt!
📂 Viewing Conversion
History
Selecting option 5 (View History) shows all past conversions:
===== CONVERSION HISTORY =====
Temp: 25.00 -> 77.00
Mass: 10.00 -> 22.05
Length: 5.00 -> 16.40
Time: 2.00 -> 120.00
This feature helps users track previous
calculations.
🚀 Why This Project is
Great for Beginners?
✔
Learn modular
programming in C
using functions.
✔ Practice file handling to store conversion history.
✔ Understand loops, conditions, and user input handling.
✔ Easily expandable (Add currency or volume
conversions!).
📌 Conclusion
The Unit
Converter in C is an excellent beginner-friendly project that introduces modular programming, data validation, and
file handling. You can improve it by adding graphical interfaces or additional unit conversions.
